摘　　要：综述了近年来生物柴油主要副产物甘油的催化选择氧化转化的研究进展。分析了甘油的化学催化选择氧化的反应网络;介绍了催化甘油选择氧化反应主要的催化剂如负载型金属催化剂、多孔材料以及有机酰基-TEMPO催化剂的催化性能及催化机理;评述了甘油氧化过程中催化反应条件等对产物选择性和反应物转化率的影响;概括了甘油的电催化氧化、甘油催化氧化聚合生成新型聚合物聚丙酮二酸盐(polyketomalonate)等新催化反应及其机理,总结了甘油生物催化氧化的产物二羟基丙酮(DHA)的新进展。最后提出了甘油催化氧化存在的一些问题,并展望了甘油催化氧化的研究和发展方向。The recent progress of research and development on the catalytically selective oxidation of glycerol which is the by-product of biodiesel processes, is reviewed. The reaction networks of catalytic oxidation of glycerol, related products and their potential applications are summarized. The developing catalysts and catalytic mechanism in the process of selectively catalytic oxidation of the glycerol are discussed. The influences of different catalysts, such as supported noble or non-noble metal catalysts, porous oxides, and reaction conditions, on selectivity to desired products and conversion of glycerol in the oxidation processes of glycerol are remarked, as well as the discussion of catalytic mechanism. The present situation of electrocatalytic selective oxidation of glycerol and novel oxidation-assisted polymerization of glycerol to polyketomalonate and related catalytic mechanism are also introduced. The recent progress on production of dihydroxyacetone （DHA） by biocatalytic oxidation of glycerol is elaborated. The pending problems and the prospects for the catalytic oxidation of glycerol are stated.
