Electrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) presents a promising approach for converting biomass derivatives into high-value chemicals but is challenging due to poor stability and low Faradaic efficiency. Herein, we present high-entropy NiCoFeMnAl layer double hydroxide (NiCoFeMnAl-LDH) HMFOR via hydrothermal method. At potential of 1.43 V vs RHE, the process demonstrates exceptional performance with 100% HMF conversion, 99.09% selectivity 2,5-furandicarboxylic acid (FDCA), efficiency 96.9%, which outperform majority previously reported state-of-the-art electrocatalysts. The impressive primarily attributed surface chemical environment that regulates p-band center lattice oxygen, thereby reducing Gibbs free energy rate-determining step accelerating kinetics charge transfer. Moreover, NiCoFeMnAl-LDH significantly mitigates common issue carbon deposition observed in traditional LDH-based materials, enhancing HMFOR. tuning oxygen provides valuable insights design high-performance
