Selective Photocatalytic Oxidative Coupling of Methane via Regulating Methyl Intermediates over Metal/ZnO Nanoparticles

Pu Wang et al.

Summary: In this study, the photocatalytic oxidative coupling of methane (OCM) over transition-metal-loaded ZnO photocatalysts was systematically investigated. A 1 wt% Au/ZnO catalyst exhibited remarkable C-2-C-4 hydrocarbon production rate and selectivity under light irradiation. The selectivity towards C-C coupling products strongly depends on the metal type and its interaction with ZnO. The findings suggest that the d-sigma center can be a suitable descriptor for predicting product selectivity during OCM over metal/ZnO photocatalysts.

Constructing hollow porous Pd/H-TiO2 photocatalyst for highly selective photocatalytic oxidation of methane to methanol with O2

Xibo Zhang et al.

Summary: In this study, a unique hollow porous nanocage structure was prepared for Pd/ H-TiO2 catalysts to selectively convert methane into methanol under mild conditions with the reaction of O2. The obtained Pd/H-TiO2 exhibited a high methanol production rate of 4.5 mmol/g/h with a selectivity of up to 70% under optimized conditions, surpassing most reported values. The mechanism study revealed the significant role of ˙OH radicals produced by photogenerated holes in the activation of methane into ˙CH3 species, which were further oxidized into methanol by ˙O2 radicals formed by photogenerated electrons. The strong metal-support interaction and unique porous hollow structure effectively enhanced the catalytic activity. These findings provide guidance for the design of high-performance photocatalysts for the selective photocatalytic oxidation of methane.

Electron redistribution of ruthenium-tungsten oxides Mott-Schottky heterojunction for enhanced hydrogen evolution

Lingxin Peng et al.

Summary: In this study, a strategy of utilizing the Mott-Schottky effect to regulate electron distribution is demonstrated for developing an effective electrocatalyst for hydrogen evolution in acid electrolyte. The hybrid Ru-WO(2.72) catalyst exhibits superior activity, with the Ru-based mass activity 161.6 times higher than that of commercial Ru/C. The enhanced hydrogen production is attributed to the electron enrichment induced by the Mott-Schottky effect at the metal-metal oxides interface.

Simultaneously Accelerating Carrier Transfer and Enhancing O2/CH4 Activation via Tailoring the Oxygen-Vacancy-Rich Surface Layer for Cocatalyst-Free Selective Photocatalytic CH4 Conversion

Pei-Pei Luo et al.

Summary: This study reports a defect-engineering strategy that selectively converts CH4 to formaldehyde through aerobic photocatalytic reactions without the use of noble-metal cocatalysts. The optimized oxygen-vacancy-rich surface disorder layer on TiO2 promotes charge carrier separation and migration, enhances the activation of O-2 and CH4, and synergistically boosts formaldehyde production. This work sheds light on the mechanism of O-2-participated photocatalytic CH4 conversion and expands the application of defect engineering in designing low-cost and efficient photocatalysts.
