Tuning electron back-donation to switch reaction pathway in CO2 hydrogenation

CO2 hydrogenation over earth-abundant Ni catalysts is attractive for CO-based fuel synthesis, but Ni intrinsically favors methanation. Here we show that ordered Ni3Sn2 intermetallics tune Ni–CO electron back-donation and switch CO2 hydrogenation from CH4 formation to the reverse...
