英文摘要: Mesoporous Ti-W oxides, bearing high surface area, large pore volume, uniform pore size and tunable W/Ti ratios in a wide range (10-40 mol%), were successfully fabricated via an evaporation-induced self-assembly (EISA) strategy. In this approach, the incorporation of W species not only effectively resulted in well-ordered mesoporous structures when calcined below 400 degrees C but also modified the acidic properties of the obtained oxide composites. The optimal acid amounts (0.47-0.67 mmol g(-1) for 400 degrees C calcinations, 0.25-0.27 mmol g(-1) for 500 degrees C calcinations) were obtained when the W concentration was between 10 and 20 mol%. When calcined at 500 degrees C, Bronsted acids were generated in Ti90W10-500 and Ti80W20-500. The catalytic performance of these mesoporous solid acids in glycerol hydrogenolysis was studied with a loading of 2 wt% Pt. Pt/Ti100-nWn-500s exhibited high selectivity to 1,3-propanediol (33.5% and 40.3%) and promising catalytic activities (18.4% and 24.2% glycerol conversion) when n is 10 and 20, respectively. This work presents a step forward in the development of highly efficient glycerol hydrogenolysis catalysts and a new understanding of the reaction mechanism of glycerol hydrogenolysis to 1,3-propanediol.
