However, the insufficient adsorption capacity of nickel-based catalysts for OH- and HMF limits their further development. In this study, amorphous Fe/NiOOH-SOx was generated from nanosheets (Fe/NiOOH-Ni3S2) that pre-fabricated on nickel foam via pre-reconstruction and anionic regulation strategy. Fe/NiOOH-Ni3S2 exhibited excellent activity for the electrooxidation of HMF (HMFOR) with a current density of 10 mA cm-2 at 1.32 V vs RHE, accompanying with the 98.9% HMF conversion, 97.8% FDCA selectivity, 96.8% Faraday efficiency, and stable stability for five cycles. The results elucidate that the introduction of amorphous FeOOH reduces the electron density around Ni, promoting the formation of high-valent Ni. Meanwhile, the SOx adsoarbs on amorphous hydroxy nickel oxide provides unsaturated sites, which enhances the adsorption capacity of HMF. Density functional theory computations demonstrate that the designed amorphous Fe/NiOOH and surface-adsorbed SOx collectively regulate the electronic structure of the catalyst, causing an upwards shift of the d-band center of NiOOH and enhancing adsorption capacities for both HMF and OH-. This work illustrates the adsorption enhancement mechanism of regulating electronic structure and provides a design strategy for HMFOR electrocatalysts.
