Semiconductor photocatalysis is a promising technology for solar fuel production and environmental remediation. However, the solar energy conversion efficiency is far from satisfactory, which restricts its practical application. The development of semiconductor materials is crucial to promote the solar energy conversion efficiency in photocatalytic systems. Owing to the Bi 6s and O 2p hybrid orbitals in the valence band, most of the bismuth-based photocatalysts possess a narrow bandgap for visible light utilization, which has attracted increasing attention. In the past few years, a rich family of bismuth-based photocatalysts have been developed, which are yet to be comprehensively reviewed. In this review article, the recent progress of bismuth-based nanomaterials for photocatalysis including pollutant degradation, water splitting, CO2 reduction, N2 fixation, and organic synthesis is critically reviewed. In particular, promising strategies for promoting the photocatalytic activity of each material system is discussed and the key challenges and prospects of bismuth-based materials for photocatalysis are presented, which are believed to promote the development of this important research field.

Construction of a visible-light-driven magnetic dual Z-scheme BiVO4/g-C3N4/NiFe2O4 photocatalyst for effective removal of ofloxacin: Mechanisms and degradation pathway

Harvesting solar energy for energy and environmental applications is an ever-fascinating field of research. Although semiconductor photocatalysis is the potential tool for recalcitrant degradation, it still suffers from rapid recombination, inability to utilize visible light, and lower photocatalytic performance. Recently, the Z-scheme photocatalysts are becoming research hotspots for their strong redox ability, charge carrier separation, and ability to exploit visible light. This review provides insights into the fundamental mechanism, synthesis strategies, and characterization techniques of Z-scheme photocatalysts. The recent advancements in their applications in visible-light-driven pollutants degradation are also reviewed.
