Efficiently converting methane (CH4) to C1 products such as CH3OH, HCHO, and CH3OOH is considered a promising route for the chemical industry, while huge challenge of low CH4 activation rate still remains. Here, Cu/ZnO composite catalyst with CuOx supported on ZnO synthesized modify electronic structure utilized conversion. The fast e– transfer channel → Cu O2 facilitates dissociation •OOH, which promotes charge separation and, in parallel, enables oxidation •CH3 by h+ left acceleration effect situ generated •OOH. Mechanistic studies revealed that additional d-π*/d-σ-orbital hybridization between adsorbed O2/CH4 molecules plays decisive roles activation, resulted highest signal, so far we know, ultimately remarkably high yield 21.25 mmol g–1 h–1 100% selectivity over optimized 1 wt % photocatalyst. This work offers valuable guidance designation conversion presence O2.

Abstract The rapid growth of the electric vehicle industry has driven up nickel demand for batteries. However, release various metals during smelting nickel‐containing ore leads to complex multi‐metal contaminated wastewater. Herein, CaFe layered double hydroxide (denoted as CaFe) is synthesized treatment wastewater, achieving removal efficiencies 98.0%, 98.6%, 100%, and 100% Co 2+ , Ni Cu Zn respectively. quasi‐situ X‐ray diffraction (XRD) absorption fine structure (XAFS) results indicate formation high‐entropy LDH CaCoNiCuZnFe by isomorphic substitution Ca in CaFe. Meanwhile, lattice distortion metal vacancies can be observed due introduction with different ionic radii dissolution . Given stability abundant active sites material, shows good OER performance an overpotential 310.7 mV at 10 mA cm −2 long‐term 250 h. Density functional theory (DFT) calculations reveal that optimizes intermediate adsorption energy enhancing M─O covalency vacancy activates oxygen generating non‐bonding oxygen, which synergistically triggers mechanism (LOM). This strategy converts wastewater resources into valuable products achieves dual goals environmental remediation resource utilization.

ABSTRACT Methane, recognized as a promising substitute for conventional fossil fuels due to its abundant availability, low cost, and high energy density, can be converted into value‐added products, providing sustainable energy–carbon utilization approach. However, inert molecules require significant C–H bond activation. Photocatalytic conversion offers an effective mild‐condition solution, reducing thermocatalysis demands enhancing activation efficiency selective chemical production. This review systematically arranges photocatalytic mechanisms, categorizes discusses challenges, prospects, solutions methane photocatalysis development.
