Tungsten and aluminum were directly incorporated into SBA-15 via one-step synthesis method under an acidic medium. The W- and Al-incorporated SBA-15 was applied as support for Pt nanoparticles to catalyze glycerol hydrogenolysis toward 1,3-propanediol. A combination of the characterization techniques showed that the tungsten and aluminum were incorporated into SBA-15 homogeneously, and the platinum nanoparticles could be uniformly dispersed on the modified-SBA-15. The catalytic performance of Pt-loaded SBA-15 could be significantly improved after the incorporation of tungsten and aluminum into SBA-15, reaching a 1,3-PDO selectivity near 50% when the glycerol conversion was 66%. The glycerol hydrogenolysis reaction proceeds through a dehydration–hydrogenation process, and the enhanced 1,3-PDO selectivity greatly benefited from the synergism between Brønsted acid and Lewis acid sites, which is tightly related with the incorporation of tungsten and aluminum species on the modified SBA-15.

使用W和铝结合的SBA-15作为Pt纳米颗粒的载体，提高1,3-丙二醇对甘油氢解的选择性

在酸性介质下，钨和铝通过一步合成方法直接掺入SBA-15中。掺有W和Al的SBA-15被用作Pt纳米颗粒的载体，以催化甘油氢解为1,3-丙二醇。表征技术的结合表明，钨和铝均匀地掺入了SBA-15中，并且铂纳米粒子可以均匀地分散在改性SBA-15上。将钨和铝掺入SBA-15中后，可以显着改善Pt负载的SBA-15的催化性能，当甘油转化率为66％时，其1,3-PDO选择性接近50％。甘油氢解反应通过脱水-氢化过程进行，增强的1
