Paper demonstrates the enhancement of photocatalytic efficiency in bismuth tungstate via various modification strategies, suggesting implications for environmental applications.
Bismuth tungstate (Bi2WO6) is a typical bismuth-based visible-light-responsive semiconductor photocatalyst that has attracted significant attention in the fields of environment remediation and energy conversion. In this paper, to address the issues of high photogenerated carrier recombination rate and limited visible-light-response range of Bi2WO6, various modification strategies are highlighted, including morphology control, element doping, heterojunction construction, carbon material compositing, and coupling with functional materials such as metal–organic frameworks (MOFs), covalent organic frameworks (COFs), or conductive polymers. Furthermore, the structure–activity relationships are discussed. On this basis, the latest application progress of Bi2WO6-based photocatalysts in fields such as pollutant degradation, antibacterial activity, and energy conversion and storage is summarized. Finally, prospects are put forward regarding the existing shortcomings and future development directions in the application of Bi2WO6-based photocatalysts, aiming to provide a systematic theoretical reference for the design and application of high-performance Bi2WO6-based photocatalysts.
