Robert GrasselliAbstract — In this pre­sen­ta­tion, I will pay trib­ute to the late Robert K. Gras­sel­li, a tru­ly extra­or­di­nary sci­en­tist who served as a ded­i­cat­ed men­tor to many indus­tri­al sci­en­tists and engi­neers, as well as a num­ber of aca­d­e­mics, such as myself. The pri­ma­ry focus of his research was on improv­ing gen­er­a­tions of com­plex oxide cat­a­lysts for pro­duc­tion of acry­loni­trile by ammox­i­da­tion of propy­lene through much of his career, and of propane in the lat­er years. The Sohio chem­i­cal catal­y­sis group, which Gras­sel­li lead for many years, suc­ceed­ed in devel­op­ing and steadi­ly improv­ing the rev­o­lu­tion­ary SOHIO process for using mul­ti­com­po­nent bis­muth molyb­dates to pro­duce a 50-fold increase in pro­duc­tion of acry­loni­trile, a plat­form chem­i­cal used for mak­ing syn­thet­ic fibers and ABS plas­tics. He became Senior Sci­ence Fel­low at the Sohio Com­pa­ny in Cleve­land, and end­ed his career there in 1985 after about 25 years of ser­vice. This was fol­lowed by 3 years as Direc­tor of the Chem­istry Divi­sion at the Office of Naval Research. From there, he moved to Mobil Research and Devel­op­ment Cor­po­ra­tion in Prince­ton, where he worked until 1995.

Robert Gras­sel­li was induct­ed into the US Nation­al Acad­e­my of Engi­neer­ing in 1995. In 1996, the Sohio acry­loni­trile process was rec­og­nized as the 11th Nation­al His­toric Chem­i­cal Land­mark by the ACS. For this work, Gras­sel­li was admit­ted to the US Engi­neer­ing and Sci­ence Hall of Fame.

Also in 1996, Gras­sel­li became an adjunct pro­fes­sor in the Cen­ter for Cat­alyt­ic Sci­ence and Tech­nol­o­gy at the Uni­ver­si­ty of Delaware; simul­ta­ne­ous­ly, he was appoint­ed as Guest Pro­fes­sor of Phys­i­cal and Cat­alyt­ic Chem­istry at the Uni­ver­si­ty of Munich. He devel­oped a num­ber of col­lab­o­ra­tions through­out the world with William A. God­dard (Cal­Tech), Sir John Meurig Thomas (Cam­bridge), Arne Ander­s­son (Lund), Johannes Lercher (Vien­na and Tri­este), Fer­ruc­cio Tri­firo (Bologne) and many oth­ers, includ­ing myself. I will dis­cuss our col­lab­o­ra­tive work start­ing with the bis­muth molyb­dates begin­ning in 1984 and, from 2002 onward, on the Mo-V-Nb-Te-O bronze “M1” cat­a­lyst for ammox­i­da­tion of propane to acry­loni­trile.

He received his PhD degree from the Pur­due Uni­ver­si­ty in 1984, and sub­se­quent­ly held the Sohio Post­doc­tor­al Research Fel­low­ship in the Depart­ment of Phys­i­cal Chem­istry at Cam­bridge Uni­ver­si­ty in 1984–85. He was a vis­it­ing assis­tant pro­fes­sor at Pur­due Uni­ver­si­ty with a 3-way joint appoint­ment in the Depart­ment of Chem­istry, Depart­ment of Physics and Astron­o­my, and the School of Mate­ri­als Sci­ence and Engi­neer­ing from 1986–87, before mov­ing to the Uni­ver­si­ty of Delaware.

Abstract — Per­ovskite-sup­port­ed Ni cat­a­lysts were pre­pared by Atom­ic Lay­er Depo­si­tion for use in CO2 and steam reform­ing of methane. Thin films of CaTiO3 were grown on MgAl2O4 and used as the sup­port. These cat­a­lysts were found to be self-regen­er­at­ing fol­low­ing redox cycling. Activ­i­ties for the ALD-pre­pared cat­a­lysts were high­er than that observed on Ni/MgAl2O4 in both steam reform­ing and dry reform­ing. More impor­tant­ly, the per­ovskite-sup­port­ed cat­a­lysts showed min­i­mal cok­ing, even upon expo­sure to dry methane at high tem­per­a­tures.

Abstract — Cat­alyt­ic oxi­da­tion of methane in the pres­ence of excess of oxy­gen is of great inter­est as a prac­ti­cal tech­nol­o­gy to reduce methane emis­sions from com­pressed nat­ur­al gas vehi­cles, engines, and tur­bines. Typ­i­cal com­mer­cial methane oxi­da­tion cat­a­lysts are alu­mi­na-sup­port­ed pal­la­di­um cat­a­lysts. When oper­at­ed at low tem­per­a­tures, these cat­a­lysts exhib­it rapid deac­ti­va­tions on stream due to water inhi­bi­tion. In addi­tion, these Pd-cat­a­lysts are sen­si­tive to sul­fur poi­son­ing, even with the pres­ence of a trace amount (≤ 1 ppm) of SO2 in the feed. Among oth­er oxide mate­ri­als, zeo­lites were also inves­ti­gat­ed as a poten­tial sup­port for pal­la­di­um – such as the effects of frame­works and exchange or impreg­na­tion meth­ods – but no sig­nif­i­cant ben­e­fits were dis­cov­ered in the past com­par­ing to con­ven­tion­al alu­mi­na-based cat­a­lysts. Here, we demon­strate the appli­ca­tion of siliceous zeo­lites (i.e. SiO2-to-Al2O3 ratio (SAR) >1200) as Pd-sup­port, the result­ing cat­a­lysts exhib­it sig­nif­i­cant­ly improved activ­i­ty and on-stream dura­bil­i­ty at low tem­per­a­tures, and are able to be regen­er­at­ed from sul­fur poi­son­ing under real­is­tic oper­at­ing con­di­tions.

Abstract — Cu-Zeo­lite SCR cat­a­lysts have emerged in the recent years as the lead­ing tech­nol­o­gy for meet­ing the chal­lenge of NOx reduc­tion in diesel exhaust. Despite their excel­lent per­for­mance and sta­bil­i­ty char­ac­ter­is­tics, inte­grat­ing this class of cat­a­lysts into an effec­tive and durable exhaust aftertreat­ment sys­tem has proved non-triv­ial. Such sys­tems must be capa­ble of oper­at­ing over a broad range of tran­sient con­di­tions, sur­vive a vari­ety of nom­i­nal and off-nom­i­nal aging expo­sures, and sus­tain their activ­i­ty over many years of active duty. This requires a detailed under­stand­ing of the reac­tion mech­a­nism and deac­ti­va­tion path­ways, and the abil­i­ty to trans­late those into reac­tion engi­neer­ing guid­ance to sys­tem design, feed­back con­trol algo­rithms, and on-board diag­nos­tics. In this pre­sen­ta­tion, we will share exam­ples from our recent find­ings relat­ed to the con­trol­ling regimes of oper­a­tion and to the deac­ti­va­tion mech­a­nisms of Cu-Zeo­lite cat­a­lysts – at the lev­el of cat­a­lyst mate­r­i­al, chem­i­cal func­tions, and over­all emis­sion reduc­tion per­for­mance in the con­text of a sys­tem which con­tains mul­ti­ple cat­alyt­ic ele­ments. We will fur­ther dis­cuss the advance­ments in the abil­i­ty to mod­el the behav­iors of healthy and deac­ti­vat­ed cat­a­lysts, and the respec­tive impli­ca­tions to sys­tem opti­miza­tion and con­trol.

Abstract — The olefin metathe­sis reac­tion was com­mer­cial­ized in the late 1960s to pro­duce eth­yl­ene and 2-butene from propy­lene in the Phillips Tri­olefin Process. The reverse reac­tion, how­ev­er, is cur­rent­ly desired due to a glob­al propy­lene short­age caused by the shift to lighter feed­stocks derived from shale gas frack­ing. Het­ero­ge­neous sup­port­ed MoOx/Al2O3 cat­a­lysts are employed for olefin metathe­sis in the Shell High­er Olefin Process (SHOP) that oper­ates between room tem­per­a­ture and ~200°C.

To probe the mol­e­c­u­lar details of the sup­port­ed MoOx/Al2O3 cat­a­lysts, a mod­ern in situ spec­troscopy approach was under­tak­en. In situ UV-vis mea­sure­ments (Eg val­ues) con­firmed the pres­ence of iso­lat­ed and oligomer­ic MoOx sur­face sites, with the lat­ter increas­ing with molyb­de­na load­ing. In situ Raman spec­troscopy revealed that at low load­ings of molyb­de­na (1 Mo atoms/nm2), only iso­lat­ed dioxo (O=)2MoO2 sur­face sites are present. As the molyb­de­na load­ing is increased (1–4.6 Mo atoms/nm2), oligomer­ic mono-oxo O=MoO4 sur­face sites co-exist with the iso­lat­ed dioxo (O=)2MoO2 sur­face sites. Above mono­lay­er load­ings (>4.6 Mo atoms/nm2), crys­talline MoO3 nanopar­ti­cles are also present. In situ IR indi­cates that the iso­lat­ed dioxo MoO4 sites are anchored at more basic HO-μ1-AlIV sur­face hydrox­yls, while the sur­face oligomer­ic mono-oxo sites are anchored to more acidic HO-μ1/3-AlV/VI sur­face hydrox­yls. Propy­lene metathe­sis at reac­tion con­di­tions sug­gest that the iso­lat­ed dioxo (O=)2MoO2 sur­face site may still be present after acti­va­tion of the mono-oxo sur­face sites with propy­lene. In situ UV-vis dur­ing propy­lene metathe­sis indi­cates that Mo+6 sites are dom­i­nant dur­ing propy­lene metathe­sis due to the pres­ence of unre­duced sur­face dioxo Mo+6O4 sites and re-oxi­da­tion of reduced Mo+4 sites by propy­lene back to Mo+6=CH2 and Mo+6=CHCH3 reac­tion inter­me­di­ates. The sur­face chem­istry was chem­i­cal­ly probed by C3H6-TPSR that ini­tial­ly formed oxy­genat­ed prod­ucts (CH3CHO, H2CO, CH3COCH3, H2O and CO/CO2) dur­ing cat­a­lyst acti­va­tion. The reac­tiv­i­ty of the acti­vat­ed cat­a­lysts to butene pro­gres­sive­ly increased with molyb­de­na load­ing, indi­cat­ing that the oligomer­ic mono-oxo MoOx sites are much more active than iso­lat­ed dioxo MoO4 sites for olefin metathe­sis. The crys­talline MoO3 nanopar­ti­cles, how­ev­er, were found to be inac­tive for metathe­sis. This pre­sen­ta­tion will address the fun­da­men­tal mol­e­c­u­lar and struc­tur­al details of the sup­port­ed MoOx/Al2O3 cat­a­lysts dur­ing propy­lene metathe­sis and estab­lish their struc­ture-activ­i­ty rela­tion­ships.

Converting CO2 via Thermocatalysis and Electrocatalysis

Abstract — Ris­ing atmos­pher­ic con­cen­tra­tion of CO2 is fore­cast­ed to have poten­tial­ly dis­as­trous effects on the envi­ro­ment from its role in glob­al warm­ing and ocean acid­i­fi­ca­tion. Con­vert­ing CO2 into valu­able chem­i­cals and fuels is one of the most prac­ti­cal routes for reduc­ing CO2 emis­sions while fos­sil fuels con­tin­ue to dom­i­nate the ener­gy sec­tor. The cat­alyt­ic reduc­tion of CO2 by H2 can lead to the for­ma­tion of three types of prod­ucts: CO through the reverse water-gas shift (RWGS) reac­tion, methanol via selec­tive hydro­gena­tion, and methane by the metha­na­tion path­way. In the cur­rent talk we will first describe our efforts in con­trol­ling the cat­alyt­ic selec­tiv­i­ty for the three prod­ucts using a com­bi­na­tion of DFT cal­cu­la­tions and sur­face sci­ence stud­ies over sin­gle crys­tal sur­faces, cat­alyt­ic eval­u­a­tion of sup­port­ed cat­a­lysts, and in-situ char­ac­ter­i­za­tion under reac­tion con­di­tions. Next, we will dis­cuss our efforts in con­vert­ing CO2 with­out using H2. This is moti­vat­ed by the fact that ~95% of H2 is gen­er­at­ed from hydro­car­bon-based feed­stocks, pro­duc­ing CO2 as a byprod­uct. We will present two approach­es to avoid using H2 for CO2 con­ver­sion. The first approach involves the uti­liza­tion of light alka­nes, such as ethane, to direct­ly reduce CO2 via the dry reform­ing path­way to pro­duce syn­the­sis gas (C2H6 + 2CO2 → 4CO + 3H2) and the oxida­tive dehy­dro­gena­tion route to gen­er­ate eth­yl­ene (C2H6 + CO2 → C2H4 + CO + H2O). The sec­ond approach is the elec­trol­y­sis of CO2 to pro­duce syn­the­sis gas with con­trolled CO/H2 ratios. We will con­clude our pre­sen­ta­tion by pro­vid­ing a per­spec­tive on the chal­lenges and oppor­tu­ni­ties in con­vert­ing CO2 via var­i­ous routes in ther­mo­catal­y­sis and elec­tro­catal­y­sis.

Abstract — Homo­ge­neous catal­y­sis is a mol­e­c­u­lar phe­nom­e­non, where the struc­ture of the cat­a­lyst plays a sig­nif­i­cant role on the activ­i­ty and selec­tiv­i­ty of a cat­alyt­ic reac­tion. Three cas­es stud­ies will be dis­cussed dur­ing the talk to explain the phe­nom­e­na. The top­ics are

  1. High puri­ty pal­la­di­um acetate vs com­mer­cial in organ­ic syn­the­sis
  2. Ir pre cat­a­lysts for C-H acti­vat­ed bory­la­tion
  3. Gen­er­a­tion of L1Pd(0) cat­a­lysts for advanced cross cou­pling.

Biog­ra­phy — Dr. Thomas J. Cola­cot received his Ph.D. in Chem­istry from IIT Madras in 1989, fol­low­ing a B.Sc. and M.Sc. in Chem­istry from the Uni­ver­si­ty of Ker­ala in 1981 and 1983, respec­tive­ly. After his doc­tor­al and post-doc­tor­al stud­ies in the US, Dr. Cola­cot went on to pur­sue an edu­ca­tion in man­age­ment, acquir­ing an MBA from Penn­syl­va­nia State Uni­ver­si­ty in 2005, while work­ing at John­son Matthey. Before join­ing John­son Matthey in 1995, Dr. Cola­cot had also worked as a Research Asso­ciate South­ern Methodist Uni­ver­si­ty (TX, USA) on a project fund­ed by Advanced Tech­nol­o­gy Pro­gram, as an Assis­tant Pro­fes­sor at Flori­da A&M Uni­ver­si­ty, and as a Post-Doc­tor­al/Teach­ing Fel­low at Uni­ver­si­ty of Alaba­ma. Hav­ing climbed up the ranks from Devel­op­ment Asso­ciate (bench chemist), Dr. Cola­cot is cur­rent­ly the Tech­ni­cal Fel­low at John­son Matthey, USA, the high­est tech­ni­cal rank for a sci­en­tist with reports from dif­fer­ent parts of the world.

As a researcher, Dr. Cola­cot has focused on many areas of homoge­nous catal­y­sis, par­tic­u­lar­ly becom­ing pro­fi­cient in pal­la­di­um-cat­alyzed cross-cou­pling. He also has exten­sive expe­ri­ence in organometal­lic and organ­ic syn­the­ses, and in process chem­istry. His work is reflect­ed in sev­er­al patents to his name, more than one hun­dred peer-reviewed pub­li­ca­tions, and numer­ous invit­ed lec­tures and sem­i­nars span­ning India, USA, Chi­na, and Europe. His recent­ly edit­ed book: New Trends in Cross Cou­pling: The­o­ry and Appli­ca­tions by the Roy­al Soci­ety of Chem­istry is wide­ly used in acad­e­mia and indus­try. Through his work, Dr. Cola­cot is cred­it­ed with being a lead­ing influ­ence in devel­op­ing excep­tion­al cat­alyt­ic sys­tems for the advance­ment of met­al-cat­alyzed syn­thet­ic organ­ic chem­istry for real world appli­ca­tions such as drug devel­op­ment, OLED’s/liquid crys­tals and agri­cul­ture. His empha­sis in design­ing cat­a­lysts and cat­alyt­ic process­es has been on their applic­a­bil­i­ty in indus­tri­al set­tings, par­tic­u­lar­ly per­tain­ing to agri­cul­ture, elec­tron­ics and med­i­cine. He is the finest exam­ple of a link between acad­e­mia and indus­try.

Dr. Colacot’s con­tri­bu­tions to the field have result­ed in many awards and acco­lades, amongst them the recent pres­ti­gious IIT Madras 2016 Dis­tin­guished Alum­nus Award for Tech­nol­o­gy Inno­va­tions and Chem­i­cal Research Soci­ety of India (2016 CRSI) Medal for out­stand­ing con­tri­bu­tions in Organometallics and Homo­ge­neous Catal­y­sis. He is the first Indi­an to be award­ed the Amer­i­can Chem­i­cal Soci­ety (ACS) Nation­al Award in Indus­tri­al Chem­istry in 2015. He also received the 2015 IPMI Hen­ry Alfred Award (2015) from the Inter­na­tion­al Pre­cious Met­al Insti­tute, spon­sored by the BASF. In 2014 he received the Indi­an Amer­i­can Ker­ala Cul­ture and Civic Cen­ter Award for his out­stand­ing con­tri­bu­tions in Applied Sci­ences. In addi­tion, he received Roy­al Soci­ety of Chem­istry 2012 Applied Catal­y­sis Award and Medal. He is also a Fel­low of the Roy­al Soci­ety of Chem­istry, UK.
