Photocatalytic Hydrogenation of Biomass-Derived Model Molecules to Value-Added Chemicals

Given the global energy crisis and the environmental issues, it is essential to explore sustainable and renewable resources as an alternative to traditional fossil fuels. Biomass can efficiently generate a range of high value-added chemicals and fuels through catalytic hydrogenation. Biomass thermocatalytic hydrogenation and hydrodeoxygenation (HDO) are effective but some of the processes are energy-intensive, while photocatalytic hydrogenation reactions of biomass provide new opportunities for their environmental friendliness and cost effectiveness. In this review, we focus on the recent advances in the production of value-added chemicals from biomass-derived molecules by photocatalytic hydrogenation means. The advantages of photocatalytic technology and the mechanism of photocatalytic hydrogenation have been introduced in detail. Subsequently, the recent research process on some typical model molecules is discussed. Then the types and constructions of the efficient photocatalyst, the influence of hydrogen source and solvent selection on the catalytic performance are summarized. Finally, the challenges and opportunities for the future photocatalytic hydrogenation of biomass are also proposed.
