Abstract Electrochemical oxidation of 5‐hydroxymethylfurfural (HMFOR) to generate high‐value chemicals under mild conditions acts as an energy‐saving and sustainable strategy. However, it is still challenging develop electrocatalysts with high efficiency good durability. Here, nickel foam (NF) supported CoCrCe(7.5%)‐LDH (layered double hydroxides) by doping Ce into CoCr‐LDH show (HMF) conversion (99%), 2,5‐furandicarboxylic acid (FDCA) yield Faraday (100%) at 1.4 V RHE . The also exhibits remarkable stability 97% HMF after 10 cycles. X‐ray absorption near‐edge spectroscopy (XANES) theoretical calculation that beneficial the formation high‐valance Co significantly facilitates electron transfer, regulates adsorption behavior intermediates, reduces Gibbs free energy barrier accelerates reaction rate. This work promotes use rare earth elements promote HMF.

Abstract In‐depth comprehension and improvement of the sluggish hydrogen evolution kinetics in alkaline media is highly important to enhance activity durability anion exchange membrane water electrolysis (AEMWE) for green production. Herein, a atom‐terminated core–shell PdH@Ru nanobamboos (NBs) developed by synergetic strategy epitaxial growth situ DMF hydrogenation. The synthesized NBs demonstrate exceptional reaction (HER) media, requiring only 14 mV overpotential at 10 mA cm −2 , surpassing those commercial Pt/C (35 mV) H‐free Pd@Ru (37 mV). Furthermore, an AEMWE device using as cathode also achieves current density 1000 − 2 ≈1.80 V 1.0 m KOH 60 °C, with continuous operation 50 h. operando spectroscopic analysis functional theory calculations suggest that insertion into induces tensile strain on Ru surface layer, altering Pd/Ru electronic structure weakening H adsorption, thereby enhancing HER efficiency. bamboo‐like hollow features numerous active sites, which contribute optimization electron/mass diffusion electrolyte. This work provides potential high‐efficiency cathodic electrocatalyst industrial

Abstract Methanol electrolysis, coupling thermodynamically favorable methanol oxidation reaction (MOR) and hydrogen evolution (HER), is a promising strategy for energy‐saving generation as compared with traditional water splitting. Pt‐based catalysts are the best choice while intrinsic activity utilization of Pt should be increased due to its high cost. Supporting engineering effective in boosting catalytic effectiveness, some novel supports diverse support effects developed accelerate kinetics improve efficiency. Herein, comprehensive review recent advances electrocatalysts methanol‐assisted production provided. The mechanism electrolysis anode MOR cathode HER first outlined, respectively. Then, performance enhancement effects, including anchoring, electronic, synergistic, strain briefly discussed. Subsequently, clarified by supports, metal oxides, phosphides, selenides, tellurides, presented, promotion effect relevant challenges future perspectives concluded last section, where most attention paid metal‐supporting their understanding study.
