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 CH 3 OH is the most desired product of photocatalytic 4 conversion. The prominent metal‐decorated photocatalyst challenging in both high yield and selectivity for products due to over‐oxidation by •OH mechanism. Here, interstitial Zn fabricated into i O induce formation atom island rapid single electron reduction 2 •OOH instead selective combination with methyl OOH. AuPd alloy simultaneously decorated on surface tuning OOH adsorption OH. synergy achieve a tandem reaction pathway (CH →CH OOH→CH OH) an unprecedented 2444 mmol g −1 h (or 8800 µmol cat ) 98.3% selectivity, which bypasses mechanism An apparent quantum efficiency 18.53% at 370 nm conversion are super reported systems. Thus, this work provides new strategy synergetic metal photocatalysts through mediate oxidation

Photooxidation of CH4 to value-added chemicals with high selectivity offers a promising pathway drive the rational utilization natural gas resources renewable energy under mild conditions. However, owing poor chemoselectivity reactive oxygen radical formation and consecutive side reactions primary products, synthesis peroxide directly from oxidation remains challenging. Here, we report single-atom ruthenium oxide-doped ZnO as highly selective photocatalyst for aerobic CH3OOH. Under optimal conditions, CH3OOH rate over Ru1Ox/ZnO reaches 321 μmol gcat–1 h–1 90.9% simulated solar irradiation. Mechanistic studies reveal that generation •OOH radicals via reduction ability prevent secondary are main advantages Ru1Ox/ZnO, accounting remarkable CH4. The Ru oxide/ZnO catalyst also exhibits alkyl hydroperoxide in photocatalytic low paraffins, which provides solution prepare single-step hydrocarbon substrates.
