Abstract — Ocean acid­i­fi­ca­tion and cli­mate change are expect­ed to be two of the most dif­fi­cult sci­en­tif­ic chal­lenges of the 21st cen­tu­ry. 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 hydro­car­bons through com­bi­na­tion of CO2 reduc­tion with Fis­ch­er-Trop­sch (FT) reac­tions. In the cur­rent talk we will dis­cuss some of our recent results in CO2 con­ver­sion via both het­ero­gen­er­ous catal­y­sis and elec­tro­catal­y­sis. Our research approach­es involve the com­bi­na­tion of DFT cal­cu­la­tions and sur­face sci­ence stud­ies over sin­gle crys­tal sur­faces, eval­u­a­tions over sup­port­ed cat­a­lysts, and in-situ char­ac­ter­i­za­tion under reac­tion con­di­tions. We will also dis­cuss chal­lenges and oppor­tu­ni­ties in this impor­tant research field.
Biog­ra­phy — Jing­guang Chen is the Thay­er Lind­s­ley Pro­fes­sor of chem­i­cal engi­neer­ing at Colum­bia Uni­ver­si­ty. He received his PhD degree from the Uni­ver­si­ty of Pitts­burgh and then car­ried out his Hum­boldt post­doc­tor­al research in Ger­many. After spend­ing sev­er­al years as a staff sci­en­tist at Exxon Cor­po­rate Research he start­ed his aca­d­e­m­ic career at the Uni­ver­si­ty of Delaware in 1998, and then took the roles as the direc­tor of the Cen­ter for Cat­alyt­ic Sci­ence and Tech­nol­o­gy and the Claire LeClaire Pro­fes­sor of chem­i­cal engi­neer­ing. He moved to Colum­bia Uni­ver­si­ty in 2012. He is the co-author of 20 US patents and over 300 jour­nal arti­cles with over 12,000 cita­tions. He received many awards, includ­ing the awards from the catal­y­sis clubs of Philadel­phia (2004), New York (2008), Chica­go (2011) and Michi­gan (2015). He recent­ly won the 2015 George Olah award from the Amer­i­can Chem­i­cal Soci­ety.
