The catalytic performance of ethanol synthesis from CO hydrogenation over CuZnX (X = Ti, Si, Al, Mg) catalysts prepared by complete liquid phase method are studied. Among these catalysts, CuZnTi catalyst has the best ethanol selectivity about 46.6%. Characterization results show that the interaction between Cu species and metal oxides is a key factor for ethanol synthesis from syngas, which is in accordance with our previous results. CuZnTi catalyst also has good repetitive performance. [GRAPHICS] .
