Abstract Electrocatalytic 5‐hydroxymethylfurfural oxidation reaction (HMFOR) can replace the kinetically slow oxygen evolution to yield high value‐added chemicals. In this study, interface engineering is constructed by modifying CeO 2 nanoparticles on Co 3 O 4 nanowires supported nickel foam (NF). The construction of heterointerface facilitate structural catalysts and charge transfer, as a result, successfully synthesized NF@Co /CeO exhibits higher conversion (98.0%), 2,5‐furandicarboxylic acid (FDCA) (94.5%), Faradaic efficiency (97.5%) at low electrolysis potential 1.40 V RHE compared NF@CeO . Density‐functional theory calculations indicate that establishment effectively regulate intermediate adsorption promote electron which greatly reduces activation energy dehydrogenation step in 5‐formyl‐2‐furancarboxylic (FFCA), promotes further FFCA FDCA, thereby improving performance HMFOR. HMFOR behavior effect deeply explored, provides guidance for future design with efficient performance.
