摘要
光催化技术是解决环境污染和能源危机的最有效手段之一。Ag3VO4是一种可见光响应的半导体材料,应用于光催化制氢和环境污染物降解。由于Ag3VO4光生载流子易复合使其光量子效率低,限制了其在实际生产中的应用。如何提高Ag3VO4的光催化活性成为当前科研人员研究热点。将Ag3VO4与其它半导体复合是提高其光催化性能有效方法。本文综述了近年来Ag3VO4基复合光催化剂类型、制备方法、光催化降解性能和反应机理等方面的研究进展,并对现有Ag3VO4基复合光催化剂存在的问题进行探讨,展望了Ag3VO4基复合光催化剂未来发展方向。
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.
