Photocatalysis has been regarded as one of the most promising and effective technologies for addressing environmental remediation and energy crisis by the utilization of the solar energy. Ag3VO4 is a type of visible light responsive semiconductor material, which has been applied in photocatalytic water splitting into hydrogen and environmental pollution degradation. However, the high recombination of photogenerated charge carriers and low quantum yield hamper its practical applications. How to boost the photocatalytc activity of Ag3VO4 has become hotspot of scientific researchers. Constructing Ag3VO4 with another semicondictor to form heterojunction photocatalyst is an efficient approach that can ameliorate the photocatalytic performance of the single Ag3VO4. The review summarizes recent research progress on the types, preparation methods, photocatalytic degradation performance and photocatalytic reaction mechanism of Ag3VO4-based composite photocatalysts. In addition, the existing problems about Ag3VO4-based composites were discussed and the future research direction of the Ag3VO4-based photocatalysts is also forecast.
