摘要
1,3.丙二醇是聚酯工业中最重要的单体之一.以甘油为原料,通过催化转化制备得到1,3.丙二醇具有重要的应用价值.本文对近年来甘油氢解制1,3.丙二醇的关键双金属催化剂研究进展进行综述,着重介绍了高效且颇具工业应用前景的Pt-W催化体系.通过综述Pt-W体系中具有不同微观结构和化学环境的W物种与Pt之间的相互作用及Pt-W双位点催化甘油氢解的构效关系,总结了原位生成的B酸活性物种对催化活性、选择性和稳定性的影响,讨论了原位B酸的来源及催化机制,最后对甘油选择氢解制1,3-丙二醇的催化剂发展进行了展望.
Abstract
1,3-propanediol is one of the most important monomers in the polyester industry.Catalytic conversion of glycerol to 1,3-propanediol has important application value.In this article,we reviewed the research progress of bimetallic catalysts for the hydrogenolysis of glycerol to 1,3-propanediol,especially emphasizing Pt-W catalytic systems with high catalytic efficiency and great industrial application prospects.By reviewing the interaction between W species,with different microstructures and chemical environments,and Pt metal,as well as the structure-performance relationship between Pt-W dual sites and glycerol hydrogenolysis,the influence of in-situ generated Bronsted acid active species on catalytic activity,selectivity,and stability was summarized,the source of in-situ generated Bronsted acid and catalytic mechanism was discussed,and finally,the development of bimetallic catalysts for selective hydrogenolysis of glycerol to 1,3-propanediol was prospected.
