The effect of titanium promotion on the catalytic performance of Rh-Mn-Li catalyst supported on PVP-modified SiO2 for C-2 (+) oxygenates synthesis from CO hydrogenation was investigated. The highest selectivity toward C-2 (+) oxygenates (51.3%) was achieved over the RML/0.5Ti/SiO2 catalyst. Characterization results indicates that the addition of Ti promotes the adsorption of geminal CO and the formation of Rh+, which is favorable for the CO insertion into metal-CHx band, and finally increases the selectivity of C-2 (+) oxygenates.
