Metal-Organic Framework-Derived Sugarcoated Haws-like AgNWs/ZIF-8/Pd for Plasmon-Promoted Photocatalytic Hydrogenation

Abstract

The conversion of biomass-derived materials into value-added products via photocatalysis holds significant promise in driving the development of renewable resources. However, since catalytic processes often require high temperatures and pressures, most catalysts are quite difficult to meet the requirements of high selectivity and high activity simultaneously. Herein, a plasmon-promoted photocatalyst, integrating Ag nanowires with metal-organic frameworks (MOFs)-confined Pd nanoparticles, is rationally designed to afford AgNWs/ZIF-8/Pd which achieve highly selective and efficient catalytic hydrogenation toward 2(5H)-Furanone under mild conditions. The plasmonic AgNWs/ZIF-8/Pd exhibited much stronger photocatalytic activity and higher selectivity compared with AgNWS/ZIF-8 and ZIF-8/Pd. The enhanced activity can be attributed to the synergistic coupling between Pd nanoparticles and AgNWs, and the possible reaction mechanism is proposed. This work provides a new approach to constructing efficient photocatalysts and offers new insights into the understanding of the influence of the plasmonic effect on photocatalytic hydrogenation reactions.
