An efficient catalyst of Cu/MIL-101 modified with CeO2 for the conversion of biomass-derived glycerol with aniline to 3-methylindole was constructed with the yield of the aimed product up to 59%. The characterizations revealed that the addition CeO2 to Cu/MIL-101 not only improved the dispersion of Cu particles, but also inhibited the sintering of active component, meanwhile, the number of weak acid sites of the catalyst was also greatly increased, which was favorable to the high selectivity of 3-methylindole. Moreover, the catalytic reaction mechanism was studied in depth, which both acetol and 1,2-propanediol were the intermediates in the synthesis of 3-methylindole.

用CeO 2改性的Cu / MIL-101的高效催化剂,用于将生物质衍生的甘油与苯胺转化为3-甲基吲哚

构建了用CeO 2改性的Cu / MIL-101的高效催化剂,用于将生物质衍生的甘油与苯胺转化为3-甲基吲哚,目标产物的收率高达59%。表征表明,向Cu / MIL-101中加入CeO 2不仅改善了Cu颗粒的分散性,而且抑制了活性组分的烧结,同时,催化剂的弱酸性部位数量也大大增加,这是因为有利于3-甲基吲哚的高选择性。此外,深入研究了催化反应机理,其中丙酮醇和1,2-丙二醇均是3-甲基吲哚合成的中间体。
