Abstract

Photocatalytic dehydrogenative coupling of biomass-derived furfuryl alcohol (FA) provides a promising route for simultaneous biomass upgrading and solar-to-chemical energy conversion. Herein, two novel isostructural Fe-containing polyoxometalates (POMs), Fe^II ₂(H₂O)₆H₁₉[Fe^III ₇Sb^V ₄(H₂O)₁₂W₆O₂₀K₂(C₄H₂O₆)₂(B-β-Sb^IIIW₉O₃₃)₆]·55H₂O (1) and Fe^II ₂(H₂O)₆Na₄H_11.8[Fe^III _8.6(H₂O)₁₆W_8.4O₂₂Na₂(B-β-Bi^IIIW₉O₃₃)₆]·41H₂O (2), were synthesized via a one-pot solvothermal method and coupled with CdS nanorods (CdS NRs) to construct hybrid photocatalysts for FA conversion under 450 nm LED irradiation. Among them, 1/CdS exhibited superior performance, achieving 78.95% FA conversion, 85.91% selectivity toward hydrofuroin (HDF), and efficient H₂ evolution (13.49 μmol). Structural and mechanistic studies revealed that the synergistic interaction between CdS NRs and Fe-containing POMs promotes charge separation and migration, thereby enhancing photocatalytic efficiency. This work highlights the potential of transition-metal-functionalized POMs for integrated biomass valorization and solar fuel production.
