Abstract<\/strong> \u2014 Ris\u00ading atmos\u00adpher\u00adic con\u00adcen\u00adtra\u00adtion of CO2<\/sub> is fore\u00adcast\u00aded to have poten\u00adtial\u00adly dis\u00adas\u00adtrous effects on the envi\u00adro\u00adment from its role in glob\u00adal warm\u00ading and ocean acid\u00adi\u00adfi\u00adca\u00adtion. Con\u00advert\u00ading CO2<\/sub> into valu\u00adable chem\u00adi\u00adcals and fuels is one of the most prac\u00adti\u00adcal routes for reduc\u00ading CO2<\/sub> emis\u00adsions while fos\u00adsil fuels con\u00adtin\u00adue to dom\u00adi\u00adnate the ener\u00adgy sec\u00adtor. The cat\u00adalyt\u00adic reduc\u00adtion of CO2<\/sub> by H2<\/sub> can lead to the for\u00adma\u00adtion of three types of prod\u00aducts: CO through the reverse water-gas shift (RWGS) reac\u00adtion, methanol via selec\u00adtive hydro\u00adgena\u00adtion, and methane by the metha\u00adna\u00adtion path\u00adway. In the cur\u00adrent talk we will first describe our efforts in con\u00adtrol\u00adling the cat\u00adalyt\u00adic selec\u00adtiv\u00adi\u00adty for the three prod\u00aducts using a com\u00adbi\u00adna\u00adtion of DFT cal\u00adcu\u00adla\u00adtions and sur\u00adface sci\u00adence stud\u00adies over sin\u00adgle crys\u00adtal sur\u00adfaces, cat\u00adalyt\u00adic eval\u00adu\u00ada\u00adtion of sup\u00adport\u00aded cat\u00ada\u00adlysts, and in-situ char\u00adac\u00adter\u00adi\u00adza\u00adtion under reac\u00adtion con\u00addi\u00adtions. Next, we will dis\u00adcuss our efforts in con\u00advert\u00ading CO2<\/sub> with\u00adout using H2<\/sub>. This is moti\u00advat\u00aded by the fact that ~95% of H2<\/sub> is gen\u00ader\u00adat\u00aded from hydro\u00adcar\u00adbon-based feed\u00adstocks, pro\u00adduc\u00ading CO2<\/sub> as a byprod\u00aduct. We will present two approach\u00ades to avoid using H2<\/sub> for CO2<\/sub> con\u00adver\u00adsion. The first approach involves the uti\u00adliza\u00adtion of light alka\u00adnes, such as ethane, to direct\u00adly reduce CO2<\/sub> via the dry reform\u00ading path\u00adway to pro\u00adduce syn\u00adthe\u00adsis gas (C2<\/sub>H6<\/sub> + 2CO2<\/sub> \u2192 4CO + 3H2<\/sub>) and the oxida\u00adtive dehy\u00addro\u00adgena\u00adtion route to gen\u00ader\u00adate eth\u00adyl\u00adene (C2<\/sub>H6<\/sub> + CO2<\/sub> \u2192 C2<\/sub>H4<\/sub> + CO + H2<\/sub>O). The sec\u00adond approach is the elec\u00adtrol\u00ady\u00adsis of CO2<\/sub> to pro\u00adduce syn\u00adthe\u00adsis gas with con\u00adtrolled CO\/H2<\/sub> ratios. We will con\u00adclude our pre\u00adsen\u00adta\u00adtion by pro\u00advid\u00ading a per\u00adspec\u00adtive on the chal\u00adlenges and oppor\u00adtu\u00adni\u00adties in con\u00advert\u00ading CO2<\/sub> via var\u00adi\u00adous routes in ther\u00admo\u00adcatal\u00ady\u00adsis and elec\u00adtro\u00adcatal\u00ady\u00adsis.<\/p>\n

He received his PhD degree from the Uni\u00adver\u00adsi\u00adty of Pitts\u00adburgh and then car\u00adried out his Hum\u00adboldt post\u00addoc\u00adtor\u00adal research in KFA-Julich in Ger\u00admany. After spend\u00ading sev\u00ader\u00adal years as a staff sci\u00aden\u00adtist at Exxon Cor\u00adpo\u00adrate Research, he start\u00aded his aca\u00add\u00ade\u00adm\u00adic career at the Uni\u00adver\u00adsi\u00adty of Delaware in 1998 and rose to the rank of the Claire LeClaire Pro\u00adfes\u00adsor of chem\u00adi\u00adcal engi\u00adneer\u00ading and the direc\u00adtor of the Cen\u00adter for Cat\u00adalyt\u00adic Sci\u00adence and Tech\u00adnol\u00ado\u00adgy. He moved to Colum\u00adbia Uni\u00adver\u00adsi\u00adty in 2012. He is the co-author of 21 US patents and over 340 jour\u00adnal pub\u00adli\u00adca\u00adtions with over 15,000 cita\u00adtions.
