Sulphur-tolerant homogeneous catalysts for the water gas shift reaction
Abstract
The transition metal carbonyls M(CO)6(M = Cr, Mo, and W) and M3(CO)12(M = Ru and Os), but not Fe(CO)5, have been found to be active homogeneous catalysts for the water gas shift reaction in the presence of a large excess of sulphides generated by sodium sulphide dissolved in aqueous methanol.
