Converting biomass-derived 5-hydroxymethylfurfural (HMF) into high-valued 2,5-bis (hydroxymethyl)furan (BHMF) via electrocatalytic hydrogenation (ECH) technology has been widely regarded as one of the most economical and eco-friendly routes. The high selectivity activity depend on reasonable regulation adsorption activation adsorbed hydrogen (H*) HMF surface electrocatalyst. Herein, we report nanoflower-like CuFe-based electrocatalysts copper foam (CF) substrates (CuFeOx/CF). BHMF was achieved optimal CuFeOx/CF with a 93.3% yield 90.1%. H*, product were observed by in situ attuned total reflection Fourier transform infrared spectroscopy (ATR-FTIR). Moreover, Raman spectra discloses reconstruction catalyst CuFe-bimetal low valence state. Density functional theory (DFT) calculations demonstrate that introducing Fe plays role regulating electronic structure Cu sites, which facilitate generation H* HMF, thus hampering occurrence dimerization. This study provides an innovative idea for rational design non-precious bimetallic ECH to produce chemicals.

Solar-driven photoelectrochemical CO2 reduction represents a promising approach for the production of renewable liquid fuel but is limited by low photocurrent, need an external bias, and carbon efficiency. This work employs TiO2-CdS/Se-ZnSe/S photoanode to drive sulfur oxidation reaction, achieving photocurrent density 12.7 mAcm-2 under AM 1.5G illumination with 87% retention after 100 h continuous operation. Furthermore, through tailoring adsorption capability *OCHO intermediate, Cu6Sn5 catalyst exhibits Faradaic efficiency 92.8% formic acid at -1.15 V in acidic media maintains stability above 90% during 120-h test. Finally, constructed system achieves bias-free HCOOH delivers yield up 172.9 µmolh-1cm-2 over 85-h long-term test, outperforming conventional solar-driven systems. These findings highlight cost-effective strategy provide valuable design concepts insights into development
