Advances in Heterogeneous Solid Catalysts for Oxidation of Glycerol to Lactic Acid

With the implementation of China''s dual carbon action plan under the new global climate agreement, it is extremely important to develop and utilize renewable biomass resources. As the main by-product of biodiesel in the production process, catalytic conversion of glycerol into various high value-added derivatives has received wide attention, among which selective oxidation of glycerol to lactic acid has great application prospects. In recent years, the catalytic oxidation of glycerol to lactic acid using solid catalysts has become a hot research topic for scholars at home and abroad. In this paper, the research status of solid catalysts for the catalytic conversion of glycerol to lactic acid is reviewed, the reaction pathway of catalytic conversion of glycerol to lactic acid is analyzed, and the factors affecting the catalyst activity are discussed. The development of related catalyst preparation is prospected.
