Mechanistic Investigations on the Phase Formation of Unary Metal Oxynitride Systems and their Photocatalytic Applications

Abstract

The urgent global need for sustainable energy solutions and environmental preservation has led to significant interest in photocatalysis as a versatile technology for energy transformation and pollution remediation. However, conventional metal oxide-based photocatalysts face inherent limitations such as high bandgap energy, low efficiency, and rapid electron-hole recombination. To overcome these challenges, metal oxynitride (MON) photocatalysts have emerged as a promising alternative, offering tunable band structures, enhanced charge separation, and improved photocatalytic activity. newline
