Electrochemically driven carbon–carbon coupling utilizing renewable electricity under ambient conditions has emerged as an innovative approach for synthesizing high-value chemicals, which still faces inherent challenges such low conversion rates and poor selectivity. While electroreducing furfural to hydrofuroin can produce high-quality biofuel, its efficiency need be promoted. Herein, Cu–Sn bimetallic catalyst been developed with a rate of >97% selectivity >67% through equilibrium the interfacial intermediate *H *fur-CHOH, exhibits greatest state-of-the-art overall performance. Characterization theoretical calculation reveal that Cu serves active site generating whose electron density decreased by introducing Sn, results in higher *fur-CHOH coverage lower energy barrier dimerization. Moreover, adding Sn also enables sluggish formation balance *H, leading reduced hydrogenation byproducts. The as-developed provides valuable insights optimizing other C–C electrocoupling reactions synthesis chemicals.

Controllable hydrogenation of carbonyl groups (C=O) is crucial for converting furfural into high-value furfuryl alcohol. Instead traditional impregnation method, a novel Cu-based catalyst (Cu/SiO2) prepared using the ammonia evaporation method (AE) efficient to alcohol under mild conditions. At reaction conditions 90 °C and 1 MPa H2, 5Cu/SiO2-AE sample showed optimal performance with higher turnover frequency (36.0 h-1) selectivity (>99.9%). After five cycles, recycled still high activity Characterization results such as XRD, H2-TPR, FT-IR, XPS that excellent catalytic was attributed formation layered copper silicate dispersion Cu species. Furthermore, resulted in ratio Cu+/(Cu0+Cu+) at reduction temperature 250 °C, which also responsible optimum activity. This work importance controllable synthesis improving copper-containing catalyst.
