Abstract
Biomass is the most bountiful renewable carbon resource on earth.Photocatalytic transformation is a promising method to utilize biomass to obtain high-value-added chemicals and it has more obvious ad-vantages compared with thermochemical and biological processes due to the milder operational con-ditions,fewer reagents and equipment.Semiconductor material is one of the most common kinds of heterogeneous biomass photocatalysts,which has the advantages of high selectivity,stable catalytic per-formance,long activation time,and low cost.In this paper,the significant research progress on the pho-tocatalytic transformation of biomass with semiconductor materials to produce high-value-added chem-icals is reviewed,and the three most typical semiconductor photocatalysts(TiO2,CdS,and g-C3N4)are detailed.The photocatalytic mechanism and photocatalytic system optimization including structural mod-ification,metal co-catalyst loading,and introduction of heterojunction are presented.Besides,the main problems,the development direction and trend of semiconductor materials in photocatalytic transforma-tions of biomass in the future are prospected,which provide guidance and inspiration for the further development of semiconductor photocatalysts and make contributions to the progress in efficient utiliza-tion of biomass.
