Semiconductor photocatalysis technology using solar energy has broad application prospects in energy conversion and environmental purification, while the photocatalytic efficiency is unsatisfactory due to limited photoresponse and recombination of charge carriers. Many researchers have made great efforts to develop new and efficient photocatalysts to solve the above problems. Among photocatalysts, bismuth-based nanomaterials have become ideal photocatalysts because of its unique layered structure, narrow band gap, better visible light response and good electron-hole separation characteristics. Particularly, appropriately modified photocatalysts shows better photocatalytic performance due to enhanced photoresponse characteristics and promoted separation and migration of electron-hole pairs. In this review, the characteristics of bismuth oxyiodate in bismuth-based photocatalysts are systematically introduced. Recent efforts for various modification strategies of bismuth oxyiodate have also been demonstrated and evaluated. Finally, this paper also briefly summarizes and forecasts the challenges and development directions of bismuth-based photocatalysts.
