Abstract — On the one hand, the prepa­ra­tion of dif­fer­ent zeo­lites, i.e. Beta and ZSM-5, in their nano­sized forms with con­trolled Si/Al molar ratios (~15–30), high sol­id yields (above 90%), and homo­ge­neous crys­tal sizes (~10–25 nm), has been achieved by using sim­ple bifunc­tion­al alkyl-sub­sti­tut­ed mono-cation­ic cyclic ammo­ni­um cations as OSDA mol­e­cules [1]. These OSDAs com­bine a cyclic part and a short alkyl-chain group (pref­er­en­tial­ly C4) and, depend­ing on the size and nature of the cyclic frag­ment, the crys­tal­liza­tion of dif­fer­ent zeo­lites can be con­trolled. The cat­alyt­ic prop­er­ties of the achieved nano­sized zeolitic mate­ri­als have been eval­u­at­ed for the methanol-to-olefins and olefin oligomer­iza­tion reac­tions [1].
On the oth­er hand, the effi­cient syn­the­sis of the small-pore CHA and AEI zeo­lites with nano­sized crys­tals (20—50 nm) has also been obtained fol­low­ing zeo­lite-to-zeo­lite trans­for­ma­tion pro­ce­dures, where high-sil­i­ca FAU mate­ri­als have been used as sil­i­con and alu­minum pre­cur­sors [2]. The nano­sized small pore zeo­lites have been eval­u­at­ed for the methanol-to-olefin reac­tion, observ­ing that their cat­a­lyst life­times are remark­ably longer than the cat­a­lyst life­times observed for con­ven­tion­al small pore zeo­lites. In addi­tion, the selec­tiv­i­ty towards dif­fer­ent light olefins, i.e. propy­lene and/or eth­yl­ene, can be max­i­mized depend­ing on the crys­talline struc­ture of the nano­sized zeo­lites.

Biog­ra­phy — Manuel Molin­er obtained his B.S. degree in Chem­i­cal Engi­neer­ing at the Uni­ver­si­ty of Valen­cia (Spain) in 2003, and com­plet­ed his Ph.D. at the Poly­tech­nic Uni­ver­si­ty of Valen­cia (UPV, Spain), in Chem­istry, under the guid­ance of Prof. Aveli­no Cor­ma in 2008. After­ward, he com­plet­ed a two-year post­doc (2008–2010) with Prof. Mark Davis at the Cal­i­for­nia Insti­tute of Tech­nol­o­gy (Cal­tech, USA).
He is a Tenured Sci­en­tist of the Span­ish Nation­al Research Coun­cil (CSIC) since 2014, where his research lies at the inter­face of het­ero­ge­neous catal­y­sis and mate­ri­als design.
Manuel Molin­er has pub­lished 70 papers in inter­na­tion­al jour­nals, and is co-inven­tor of 24 inter­na­tion­al patents (14 trans­ferred to indus­try). He has received dif­fer­ent nation­al and inter­na­tion­al awards, as the “EFCATS The­sis Award” to the best Ph.D. The­sis in Europe in 2007–2009, the “TR-35 Spain 2011” award­ed by MIT to young tal­ents in Spain under-35, or the “FISOCAT 2014” to young sci­en­tists under 40 in Latin Amer­i­ca.
