ELECTRONIC EFFECTS OF ADDITIVES ON THE SELECTIVITY IN CO/H2 REACTION OVER NICKEL CATALYSTS

Article abstract of DOI:10.1246/cl.1983.565

It was found with CO/H2 reaction over unsupported Ni catalysts that the C2+/CH4 selectivity decreased in the order; Ni-boride > Raney-Ni > Decomposed-Ni ca.Ni-phosphide.This suggests that both the activity and selectivity increase as the electron density on Ni metal increases.The H/C atomic ratio of the surface carbon species deposited during the reaction was also dependent on the catalyst.
