Abstract:In this paper， it was summarized that the main-reaction （for example hydrolysis， isomerization， retro-aldol， and hydride shift， etc.） and side-reaction （for example dehydration and condensation， etc.） pathways involved in the catalytic conversion of carbohydrates （three-carbon， five-carbon， six-carbon sugars， and cellulose） to lactic acid/lactates by Lewis acid （L acid） and Brønsted acid （B acid） in conventional catalytic systems （homogeneous and heterogeneous）， and corresponding relationships between structure of different catalysts and their catalytic efficiencies. Based on the materials of metal-organic framework （MOF）， tin-based silicates and graphitized carbon nitride， the latest research progress in constructing new heterogeneous and photocatalytic systems were reviewed. The future development trend of multifunctional catalysts （including L acid， B acid， binding groups， and multi-level pore structure） was prospected.
