Advanced strategies for promoting the photocatalytic performance of FeVO4 based photocatalysts: A review of recent progress

Photocatalytic technology has been considered a promising route to solve energy and environmental crises. To date, numerous efforts have been focused on exploring highly efficient photocatalysis. Among them, ferric vanadate (FeVO4) based photocatalysts are emerging as promising candidates because of their low-cost synthetic process, excellent visible light-responsive activity, and favorable conduction and valence band edge positions. However, low carrier separation efficiency is a major weakness of FeVO4. To address this problem, various modification strategies have been proposed and implemented to design efficient FeVO4 based photocatalysts and improve their photocatalytic activity, including morphological regulation, element doping and composite construction. In this review paper, we summarize the most recent advances in the design of FeVO4-based photocatalysts. It is expected that our present review work will provide insights in the direction of future FeVO4-based photocatalyst design.
