主　　题：CO hydrogenation ethanol Rh catalyst vanadium promoter 

摘      要：The influence of VOCl2 additive in the supported Rh catalysts derived from both Rh2 (CO )4 Cl2 and RhCl3 on CO hydrogenation was investigated. The VOCl2 additive as a promoter can effectively enhance the CO conversion and catalytic selectivity to ethanol. This effect is caused by the interaction of Rh with vanadium promoter. It is found that the Rh centers on which the gem- adsorbed CO could be formed are main active sites. The Rh2(CO)4Cl2 complex is better than the RhCl3 salt as the precursor of the Rh catalyst for the CO hydrogenation to ethanol.
