Abstract The low‐energy electrochemical production of hydrogen peroxide (H 2 O ) has garnered significant attention as a viable alternative to traditional industrial routes, with the goal achieving carbon neutrality. For their H selectivity in two‐electron oxygen reduction reaction (ORR), coordination environment tungsten (W)‐based materials is critical. In this study, atomically dispersed W single atoms were immobilized on N‐doped substrates by facile pyrolysis method obtain single‐atom catalyst (W‐SAC). an isolated atom tetra‐coordinated porphyrin‐like structure W‐SAC was determined X‐ray photoelectron spectroscopy and absorption analysis. Notably, as‐prepared showed superior ORR activity 0.1 M KOH solution, including high onset potential (0.89 V), (82.5%), excellent stability. By using differential phase contrast‐scanning transmission electron microscopy density functional theory calculations, it revealed that charge symmetry‐breaking changes adsorption behavior intermediates, leading enhanced reactivity for ORR. This work broadens avenue understanding transfer W‐based electrocatalytic in‐depth mechanism SACs

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.

This work aims to explore the influence of crystal phase engineering on photocatalytic hydrogen evolution activity Ru/C3N4 systems. By precisely tuning combination Ru precursors and reducing solvents, we successfully synthesized co-catalysts with distinct phases (hcp fcc) integrated them C3N4. The experiments demonstrated that hcp-Ru/C3N4 achieved a significantly higher rate (24.23 μmol h−1) compared fcc-Ru/C3N4 (7.44 h−1), reaching approximately 42% Pt/C3N4 under same conditions. Photocurrent electrochemical impedance spectroscopy analyses revealed exhibited superior charge separation transfer efficiency. Moreover, Gibbs free energy calculations indicated adsorption hcp-Ru (ΔGH* = −0.14 eV) was closer optimal fcc-Ru (−0.32 eV), enhancing generation process. These findings highlight crystal-phase plays critical role in electronic structure catalytic properties Ru-based systems, offering insights for design highly efficient noble metal catalysts photocatalysis.
