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

ABSTRACT The Ni/CeO 2 catalyst stands out among various solid metal oxide catalysts for its exceptional catalytic proficiency, positioning it as a prime candidate the industrialization of methanation processes. This review thoroughly examines prevalent challenges associated with in reactions, compiles current strategies to overcome these hurdles, and presents novel perspectives. elucidates structural characteristics applications discusses synthesis methods their respective merits demerits, explores reaction systems at both laboratory industrial scales, clarifies underlying mechanisms. Furthermore, underscores mainstream approaches enhance low‐temperature activity mitigate decrement due Ni agglomeration. concludes by proposing future directions improving preventing deactivation, encompassing development innovative architectures, integrating in‐situ characterization theoretical calculations, investigating photothermal systems. Undoubtedly, scientific researchers will persistently strive develop high across broad temperature range robust stability, driving CO technology foreseeable future.
