As one of the most abundant renewable resources on the earth, non-food biomass has the potential to replace fossil resources for production of high-value chemicals and green energy. Photoinduced catalysis has attracted wide attention as active species are generated under mild conditions to trigger the transformations. In this paper, the major photoinduced catalytic systems for biomass-related transformations in both homogeneous catalysis and heterogeneous catalysis are systematically reviewed. Radicals are generated under light irradiation to induce cleavage of C—C and C—O bonds related with cellulose, hemicellulose and lignin, the main components of biomass, to drive the further transformations. This review could provide insights for design of highly efficient and selective photoinduced catalytic biomass conversion systems. Summary and the prospects are given for the further development.

Key words: biomass, photocatalysis, radicals, C—C bond cleavage, C—O bond cleavage
