Abstract

Abstract Electrochemical reduction of biomass‐derived 5‐hydroxymethylfurfural (HMF) represents an elegant route toward sustainable value‐added chemicals production that circumvents the use of fossil fuel and hydrogen. However, the reaction efficiency is hampered by the high voltage and low activity of electrodes (Cu, Bi, Pb). Herein, we report a Ru 1 Cu single‐atom alloy (SAA) catalyst with isolated Ru atoms on Cu nanowires that exhibits an electrochemical reduction of HMF to 2,5‐dihydroxymethylfuran (DHMF) with promoted productivity (0.47 vs. 0.08 mmol cm −2 h −1 ) and faradic efficiency (FE) (85.6 vs. 71.3 %) at −0.3 V (vs. RHE) compared with Cu counterpart. More importantly, the FE (87.5 %) is largely…
