Cobalt–Nickel Catalysts for Selective Hydrogenation of Carbon Dioxide into Ethanol

Selective hydrogenation of CO2 into valuable ethanol proceeds by the coupling of appropriate C1 intermediates to form C2-oxygenates. Matching the different C1 intermediates is crucial for this process but is difficult to control. We found that incorporation of nickel species into the cobalt catalyst could boost the formation of relatively stable *CHx intermediate from CO2 hydrogenation, which significantly avoids an occurrence of methanation....
