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.
