Selective superoxide radical generation for glucose photoreforming into arabinose
文献摘要：
Biomass photorefinery to produce fuels and valuable chemicals is a promising approach to alleviating the energy crisis and achieving carbon neutrality.However,precisely modulating the photocatalytic conver-sion of biomass into value-added chemicals is still challenging.Here we demonstrate a feasible strategy to selectively produce arabinose via oriented glucose oxidation to gluconic acid,followed by the decar-boxylation process for Cl-C2 bond cleavage.To realize this process,gold nanoparticles(Au NPs)modified carbon nitride(AuCN)is rationally designed to regulate the electron transfer behavior of pristine carbon nitride from a two-electron pathway to a single-electron pathway.This allows selective production of superoxide(.O2-)from oxygen reduction reaction which triggers glucose oxidation into gluconic acid.In addition,the arabinose production is synergistically promoted by the improved charge separation effi-ciency and extended visible-light absorption via localized surface plasmon resonance(LSPR)of Au nanoparticles.This work demonstrates an example of a mechanism-guided catalyst design to improve biofuels/chemicals production from biomass photorefinery.
