Abstract:

Biomass-derived alcohol/aldehydes are important platform compounds, which can be further converted into high-value-added chemicals or fuels through catalytic oxidation. Photoelectrocatalytic(PEC) technology driven by solar energy is one of the most green and efficient ways to realize the oxidation of biomass-derived alcohol/aldehydes. Compared with the traditional PEC water splitting process to produce both O2 and H2, the use of PEC oxidation of biomass-derived alcohol/aldehydes instead of anodic oxygen evolution process can not only increase the value of anodic products, but also improve the conversion efficiency of solar energy to hydrogen, which is of great significance for H2 production and high value chemical synthesis. In this review, we introduce the reaction mechanism of PEC H2 production coupled with biomass-derived alcohol/aldehyde oxidation, and summarize the recent progress in PEC oxidation of biomass-derived alcohol/aldehydes. Moreover, the opportunities and challenges in this field are also prospected.
