Advances in the Synthesis and Applications of Transition/Noble Metal Oxide Photocatalysts

The reprint "Advances in the Synthesis and Applications of Transition/Noble Metal Oxides Photocatalysts", published in Catalysts, presents recent scientific achievements in the field of photocatalysis and the application of semiconductor photocatalysts for solving environmental problems, particularly in wastewater treatment and the removal of organic pollutants. Special emphasis is placed on the limitations of conventional semiconductor materials, such as the rapid recombination of photogenerated electron-hole pairs (e¿/h¿), low quantum yield, and high band gap value, which reduce the efficiency of photocatalytic processes. Particular attention is given to surface modification with transition and noble metals and their oxides as an effective approach to improving charge separation, suppressing recombination, and enhancing photocatalytic activity. The included studies address novel synthesis methods, structural engineering, and practical applications of these materials in environmental technologies. The reprint brings together current trends and innovative solutions in the development of sustainable and highly efficient photocatalytic systems with strong potential for broad application in environmental protection.
