摘要： Achieving sustainable energy and chemical production has become an important issue for human society. Photocatalysis has attracted much attention due to its ability to harness solar energy to drive chemical reactions. Metal sulfide-based photocatalysts (e.g., CdS, ZnIn2S4) have shown substantial potential in biomass-based hydroxyl compound valorization. In this review, we summarize the recent progress in metal sulfide-based photocatalysts for the photo upgrading of biomass-derived hydroxyl compounds coupled with reduction reactions (e.g., CO2 reduction, H2O2 generation, and H2 evolution). The mechanism of biomass redox reactions is discussed, highlighting the potential of realizing the valorization of biomass-derived compounds coupled with the reduction reactions, which is beneficial for researchers to actively explore biomass biorefinery pathways in order to modulate the selectivity of the valueadded products. Various modification strategies are presented, including elemental doping, defect engineering, heterojunction construction, and cocatalyst loading. These strategies modulate the energy band structure, surface electron density, and built-in electric field strength of metal sulfide-based photocatalysts, thereby enhancing their photocatalytic performance. The challenges and prospects of metal sulfide-based photocatalysts in biomass valorization are analyzed. This approach contributes to the development of photocatalysts that can accelerate biomass photo-upgrading coupling reactions. This review aims to provide deeper insights into the photocatalytic biorefinery pathways and contribute to the development of functionalized photocatalysts that can accelerate biomass photo upgrading, highlighting the synergistic effects of multiple coupling reactions.
