\nAbstract<\/strong> \u2014 Mixed oxide cat\u00adalyt\u00adic mate\u00adri\u00adals pos\u00adsess two or more met\u00adal oxide com\u00adpo\u00adnents as found in bulk mixed met\u00adal oxides (sto\u00adi\u00adchio\u00admet\u00adric oxides as well as sol\u00adid solu\u00adtions), poly\u00adoxo meta\u00adlates (POMs), mol\u00ade\u00adc\u00adu\u00adlar sieves, zeo\u00adlites, clays, hydro\u00adtal\u00adcites and sup\u00adport\u00aded met\u00adal oxides. Although it is now well estab\u00adlished that two-dimen\u00adsion\u00adal sur\u00adface met\u00adal oxide phas\u00ades are present for sup\u00adport\u00aded met\u00adal oxides on tra\u00addi\u00adtion\u00adal sup\u00adports (e.g., Al2<\/sub>O3<\/sub>, TiO2<\/sub>, ZrO2<\/sub>, SiO2<\/sub>, etc.), it is not cur\u00adrent\u00adly appre\u00adci\u00adat\u00aded that such sur\u00adface met\u00adal oxide species or phas\u00ades are also present for oth\u00ader types of mixed oxides. For exam\u00adple, recent sur\u00adface analy\u00adses have demon\u00adstrat\u00aded that sto\u00adi\u00adchio\u00admet\u00adric bulk mixed met\u00adal oxides also pos\u00adsess sur\u00adface met\u00adal oxide phas\u00ades that con\u00adtrol their cat\u00adalyt\u00adic activ\u00adi\u00adty. For exam\u00adple, the cat\u00adalyt\u00adic active sites for methanol oxi\u00adda\u00adtion to formalde\u00adhyde over the bulk Fe2<\/sub>(MoO4<\/sub>)3<\/sub> mixed oxide cat\u00ada\u00adlyst are sur\u00adface MoOx<\/sub> species and not the bulk Fe2<\/sub>(MoO4<\/sub>)3<\/sub> phase as pre\u00advi\u00adous\u00adly thought in the catal\u00ady\u00adsis lit\u00ader\u00ada\u00adture. The nanome\u00adter sized clus\u00adters in POMs also pos\u00adsess sur\u00adface species when a sec\u00adond met\u00adal oxide com\u00adpo\u00adnent is intro\u00adduced (e.g., H3<\/sub>+xPW12<\/sub>-xMx<\/sub>O40<\/sub>). Depo\u00adsi\u00adtion of met\u00adal oxides into mol\u00ade\u00adc\u00adu\u00adlar sieves, zeo\u00adlites, clays and hydro\u00adtal\u00adcites also results in the met\u00adal oxide addi\u00adtive usu\u00adal\u00adly being present as sur\u00adface met\u00adal oxide species that are the cat\u00adalyt\u00adic active sites for many redox and acid reac\u00adtions. The for\u00adma\u00adtion of these sur\u00adface met\u00adal oxide phas\u00ades is dri\u00adven by their low sur\u00adface free ener\u00adgy and low Tam\u00admann tem\u00adper\u00ada\u00adture for many met\u00adal oxides of inter\u00adest in catal\u00ady\u00adsis (e.g., VOx<\/sub>, MoOx<\/sub>, CrOx<\/sub>, ReOx<\/sub>, WOx<\/sub>, etc.).

He received sev\u00ader\u00adal recog\u00adni\u00adtions upon grad\u00adu\u00ada\u00adtion (AIChE Award for Out\u00adstand\u00ading Senior, Heller Memo\u00adr\u00adi\u00adal Award for Out\u00adstand\u00ading Scholas\u00adtic Achieve\u00adment, and White ChE Alum\u00adni Award). He con\u00adtin\u00adued his grad\u00adu\u00adate ChE edu\u00adca\u00adtion at Stan\u00adford Uni\u00adver\u00adsi\u00adty under the men\u00adtor\u00adship of Pro\u00adfes\u00adsor Robert J.

\nINDUSTRIAL YEARS (1977\u20131986) \u2014 Israel joined Exxon Research &<\/span> Engi\u00adneer\u00ading Com\u00adpa\u00adny in their Cor\u00adpo\u00adrate Research Labs towards the end of 1977. At Exxon, he was involved with many dif\u00adfer\u00adent cat\u00adalyt\u00adic tech\u00adnolo\u00adgies over the years (selec\u00adtive oxi\u00adda\u00adtion, acid catal\u00ady\u00adsis, syn\u00adthe\u00adsis of syn\u00adthet\u00adic fuels, hydrodesul\u00adfu\u00adr\u00adiza\u00adtion (HDS) and hydro\u00adcar\u00adbon con\u00adver\u00adsion). He obtained 100 USA and inter\u00adna\u00adtion\u00adal patents dur\u00ading his indus\u00adtri\u00adal career. One of his inven\u00adtions on the selec\u00adtive oxi\u00adda\u00adtion of o-xylene to phthal\u00adic anhy\u00addride became the lead\u00ading inter\u00adna\u00adtion\u00adal indus\u00adtri\u00adal cat\u00ada\u00adlyst for this tech\u00adnol\u00ado\u00adgy and is still used around the world. At Exxon, he received the Research Incen\u00adtive Award for one of his inven\u00adtions on the syn\u00adthe\u00adsis of syn\u00adthet\u00adic fuels and was also select\u00aded to be an Exxon Fel\u00adlow for the spring semes\u00adter of 1986 at Cal\u00adi\u00adfor\u00adnia Insti\u00adtute of Tech\u00adnol\u00ado\u00adgy (Cal\u00adTech). He depart\u00aded for acad\u00ade\u00admia at the end of 1986.

\nACADEMIC YEARS (1987-present) \u2014 He joined the Chem\u00adi\u00adcal Engi\u00adneer\u00ading Depart\u00adment of Lehigh Uni\u00adver\u00adsi\u00adty in Jan\u00adu\u00adary 1987. At Lehigh, he taught many dif\u00adfer\u00adent cours\u00ades over the years: Het\u00adero\u00adge\u00adneous Catal\u00ady\u00adsis, Reac\u00adtor Engi\u00adneer\u00ading, Flu\u00adid Mechan\u00adics, Pro\u00adfes\u00adsion\u00adal Devel\u00adop\u00adment, Unit Oper\u00ada\u00adtions, Envi\u00adron\u00admen\u00adtal Catal\u00ady\u00adsis, and Air Pol\u00adlu\u00adtion Con\u00adtrol.

This is reflect\u00aded in the many nation\u00adal and inter\u00adna\u00adtion\u00adal hon\u00adors he has received over the years as well as ~17,000 cita\u00adtions to his pub\u00adli\u00adca\u00adtions with an H-index of 70 (one of the high\u00adest among het\u00adero\u00adge\u00adneous catal\u00ady\u00adsis researchers).<\/p>\n
