(1 mmol), 100 °C, and 30 bar air pressure. Xing and co-workers designed and synthesized a dual-function RuSA-RuO2/TiO2 photocatalyst and evaluated it in the coproduction of hydrogen and benzaldehyde from benzyl-alcohol aqueous H2O solution. Surprisingly, the photocatalyst showed enhanced separation efficiency of photogenerated electrons and holes as well as afforded efficient active sites for hydrogen evolution and selective oxidation of benzyl alcohol. All in all, considering the above-mentioned shortcomings of conventional selective oxidation and the urgent need for sustainable social and environmental development, the development of safe and highly only base catalytic selective oxidation protocols that are usable under open-air systems in benign solvent water is highly desirable, and remains unwell developed.
