RATIONAL DESIGN OF OXIDE CATALYSTS FOR CARBON DIOXIDE ACTIVATION AND HYDROGENATION

摘要

Carbon dioxide (CO2) reduction to chemicals and fuels is a promising approach to addressing concerns over decreasing supplies of fossil fuels and mitigating the effects of greenhouse gas emissions on global climate change. CO2 hydrogenation on metal oxide catalysts produces formic acid, formaldehyde, methanol, and methane in a series of proton-coupled electron transfer steps. The kinetics of these steps, however, should be quantified to determine the rate-limiting step(s) and the effect of catalyst structure and composition on the preferred reaction pathways.
