摘要： 采用蒸发诱导自组装法制备了介孔氧化钨 (m-WO3), 担载 Pt 后应用于催化甘油氢解制 1,3-丙二醇. 结果表明, 与商业氧化钨 (c-WO3) 相比, m-WO3 具有高比表面积和易还原的优点, 从而使得 Pt 纳米粒子高度分散于其上. 在 180 oC 和 5.5 MPa H2 下反应 12 h, Pt/m-WO3 催化剂上甘油转化率和 1,3-丙二醇的选择性分别为 18.0% 和 39.2%, 明显高于 Pt/c-WO3 催化剂.

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.
