Abstract Since formaldehyde oxidation reaction (FOR) can release H 2 , it is attractive to construct a bipolar hydrogen production system consisting of FOR and evolution (HER). Although copper‐based catalysts have attracted much attention due their low cost high activity, the performance enhancement mechanism lacks in‐depth investigation. Here, an amorphous‐crystalline catalyst amorphous nickel hydroxide‐coated copper dendrites on foam (Cu@Ni(OH) /CF) prepared. The modification Ni(OH) resulted in hydrophilic aerophobic states Cu@Ni(OH) /CF surface, facilitating transport liquid‐phase species electrode surface accelerating . Open circuit potential (OCP) density functional theory (DFT) calculations indicate that this core–shell structure facilitates adsorption HCHO OH − In addition, catalytic pathway are investigated through situ FTIR DFT calculations, results showed lowered energy barrier for C─H bond breaking H─H formation. HER//FOR system, Pt/C//Cu@Ni(OH) provide current 0.5 A cm −2 at 0.36 V achieve efficient stable production. This work offers new ideas designing electrocatalysts assisted with oxidation.

High-entropy alloys (HEAs) present both significant potential and challenges for developing efficient electrocatalysts due to their diverse combinations compositions. Here, we propose a procedural approach that combines high-throughput experimentation with data-driven strategies accelerate the discovery of HEA hydrogen evolution reaction (HER). This enables rapid preparation arrays various element composition ratios within model system. The intrinsic activity is swiftly screened using scanning electrochemical cell microscopy (SECCM), providing precise composition-activity data sets An ensemble machine learning (EML) then used predict database subspace Based on these results, two groups promising catalysts are recommended validated through actual electrocatalytic evaluations. approach, which strategies, provides new pathway electrocatalysts.

Abstract Strain effects have garnered significant attention in catalytic applications due to their ability modulate the electronic structure and surface adsorption properties of catalysts. In this study, we propose a novel approach called “similar stacking” for stress modulation, achieved through loading Co 2 P on Ni (Ni P/Co P). Theoretical simulations reveal that compressive strain induced by influences orbital overlap electron transfer with hydrogen atoms. Furthermore, number stacked layers can be adjusted varying precursor soaking time, which further modulates range adsorption. Under 2‐h condition, effect proves favorable efficient production. Experimental characterizations using X‐ray diffraction, high‐angel annular dark‐field scanning transmission election microscope (HAADF‐STEM), absorption near‐edge spectroscopy successfully demonstrate lattice contraction bond length shortening Co–P. Remarkably, our catalyst shows an ultrahigh current density 1 A cm −2 at overpotential only 388 mV, surpassing commercial Pt/C, while maintaining long‐term stability. This material design strategy similar stacking opens up new avenues modulation deeper development electrocatalysts.
