Research Progress on Bismuth-Based Semiconductors in Photocatalysis

Abstract

With the escalating global energy crisis and environmental pollution, photocatalysis technology has emerged as a promising new avenue for development. Bismuth-based semiconductors have garnered attention as focal subjects of research in the scientific community for advancing photocatalysis technology. This article begins by introducing the crystal structure, optical properties, and electronic structure of each bismuth-based semiconductor, elaborating on their key attributes in photocatalytic applications. Through a discussion of the diverse applications of different bismuth-based semiconductors in photocatalysis, including organic compound degradation, water splitting for hydrogen generation, and redox reactions, the article analyzes their photocatalytic performance, stability, and mechanisms. This provides readers with a comprehensive understanding of the potential and limitations of these materials in practical applications. Finally, the article summarizes the challenges present in current research and outlines future directions, advocating for further exploration and innovation to propel the application of bismuth-based semiconductors in fields such as clean energy and environmental purification.
