A series of bimetallic Cu samples (Cu-Pt/SiO2, Cu-Pd/SiO2, Cu-Ag/SiO2, Cu-Ni/SiO2) were prepared by wetness impregnation method, then investigated for hydrogenolysis of glycerol to 1,2-propanediol (1,2-PDO). We furthered the study and found that Cu-Pt/SiO2 got the smallest particle size and greatest dispersion. Besides, it was found that Pt promoted reduction of Cu2+. Compared with other Cu-Pt molar ratio, Cu-Pt/SiO2 (1:0.2) was the preferable catalyst for hydrogenolysis of glycerol to 1,2-PDO. It is worth noting that Cu-Pt/SiO2 presented the highest activity with a 96 % selectivity to 1,2-PDO and a nearly 100 % conversion of glycerol at 473 K, 40 bar initial H-2 pressure, 12 h, which is much higher activity than monometallic Cu/SiO2, Pt/SiO2 and other bimetallic Cu samples. Meanwhile, the used Cu-Pt/SiO2 catalyst still preformed high activity. Furthermore, it was found that the presence of Pt decreased the aggregation of particles during the hydrogenolysis of glycerol.
