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
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 model molecules using
photocatalytic hydrogenation and photocatalytic reactions involving active hydrogen.
The advantages of photocatalytic technology and the mechanism of photocatalytic hydrogenation
have been introduced in detail. Subsequently, the recent research process on the conversion
of 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.
