  "abstract": "The direct conversion of CH₄ into liquid oxygenates via heterogeneous catalysis is highly challenging due to the facile overoxidation of target products. Herein, we present a potential Ag-modified In₂O₃ photo-thermal catalyst that enables the selective oxidation of CH₄ to CH₃OH and HCHO using molecular O₂ under mild conditions (150°C, Xe lamp irradiation). The optimized Ag-3/In₂O₃ catalyst exhibits remarkable performance, achieving 100% selectivity toward liquid oxygenates with complete suppression of CO₂ formation, and delivers a high production rate of 6544 μmol · g⁻¹ · h⁻¹, 2.6 times greater than that under pure photocatalysis at 25°C. Mechanistic studies reveal that photogenerated holes facilitate C-H bond activation to form ·CH₃ radicals, while O₂ is selectively reduced at electron-rich Ag sites to generate ·OH species. Meanwhile, it is demonstrated that excessive ·OH generation on the Ag-10/In₂O₃ contrast catalyst promotes HCHO overoxidation to CO₂, highlighting the importance of ·OH regulation in determining product selectivity over the Ag-3/In₂O₃ catalyst. Moreover, combined with experiments and DFT calculations, the results demonstrate that In₂O₃ with a suitable band structure exhibits weak adsorption affinity toward CH₃OH and HCHO, while also providing an in-depth understanding of the zero CO₂ emissions in this catalytic process. The work illustrates that the strategic coupling of thermal and photocatalytic pathways enhances charge-carrier utilization and promotes selective radical chemistry for efficient CH₄ valorization.",
