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.
