Abstract: Mesoporous tungsten trioxide (m-WO3) was prepared using an evaporation-induced self-assembly method and was used as the support of Pt for hydrogenolysis of glycerol to produce 1,3-propanediol. In comparison with commercial WO3, the m-WO3 presents a much larger surface area and better reduciblity, which make the Pt particles highly dispersed on the support. At a reaction condition of 180 oC, 5.5 MPa H2, and reaction time of 12 h, the Pt/m-WO3 catalyst afforded 18.0% conversion of glycerol and 39.2% selectivity for 1,3-propanediol, both of which are much higher than those on commercial Pt/WO3 catalyst.

Key words: mesoporous tungsten trioxide, platinum, glycerol, hydrogenolysis, 1,3-propanediol
