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.
