Abstract: Aqueous-phase reforming of biomass-derived polyols is one of the ongoing and promising technologies for hydrogen production. In this paper，the recent advance in hydrogen production by aqueous-phase reforming of biomass-derived polyols is reviewed. First，the thermodynamic and kinetic considerations that form the basis of the process are discussed. Then，the reaction pathways and the catalytic system as well as the optimization of technological conditions are introduced. In comparison with the process of steam reforming，the advantages and disadvantages of aqueous-phase reforming are proposed. On the one hand，the technology of aqueous-phase reforming possesses the features of lower energy consumption，less processing steps and relatively simple post-processing. On the other hand，there are more side reactions and the yield of H2 is lower. Finally，the review points out that the research directions are the development of more effective and stable catalysts，and the reduction of the cost for catalysts preparation and the optimization of the processing condition in the future.
