Biomass-Derived Sustainable Dual-Atom Catalysts Enabled Highly Efficient Electrochemical Reductive Ring-Opening of 5-Hydroxymethylfurfural to 2,5-Hexanediol

, alongside an impressive Faradaic efficiency of 90.2%. This performance surpasses that of previously reported systems by an order of magnitude, highlighting its significant economic potential, as evidenced by comprehensive technoeconomic analysis. In situ electrochemical characterizations, combined with theoretical studies, suggest that the ERR of HMF is induced by surface-adsorbed hydrogen through a concerted proton-electron transfer mechanism. The outstanding catalytic performance is attributed to the synergistic interaction between Cu and Zn active sites in the dual-atom catalyst. This study provides a promising electrochemical reductive approach for the efficient conversion of biomass derivatives into high-value chemicals and achieves comprehensive utilization of biomass resources.
