| Abstract: | The electrooxidation of 5‐hydroxymethylfurfural (HMF) has emerged as a promising way to generate high‐value‐added bio‐based products. However, improving catalyst selectivity for HMF and inhibiting competitive oxygen evolution reaction (OER) in a limited potential range remain long‐term targets. In this work, the self‐supported LIG‐NiCuP electrode, utilizing a porous laser‐induced graphene (LIG) skeleton as the substrate and loaded with NiCuP compound, is designed for the efficient and highly selective electrooxidation of HMF to 2,5‐furandicarboxylic acid (FDCA). The surface reconstruction of electrode forms a LIG‐NiCuP/NiCu(OH)x heterostructure, demonstrating high activity (HMF conversion 99.7%, FDCA yield 92.6%) for HMF oxidation reaction (HMFOR). Studies indicate that the low activity of Cu for OER allows it to function as a co‐catalyst, enhancing the selectivity of Ni‐based primary catalyst for HMF. In addition, the pine needle‐like structure introduced by Cu can optimize the morphology of catalyst deposited on the LIG skeleton, increasing the contact area with HMF. On the other hand, from the point view of the substrate to support metal catalysts, the fabrication of LIG combines the characteristics of rapidity, simplicity, scalability, and low cost, therefore, holding high promise in practical applications. Overall, the material system and processing method in this work present a significant step toward developing efficient catalyst electrodes for biomass conversion. [ABSTRACT FROM AUTHOR] |
