As a fascinating visible-light driven photocatalyst, silver (meta)vanadate with the merits of narrow band gap, well crystallization and easy preparation has been a hotspot in the field of photocatalysis. Generally, pristine silver (meta)vanadate suffers from photocorrosion, high recombination rate of photogenerated e⁻-h⁺ pairs, poor quantum yield and insufficient sunlight absorption, resulting in poor photocatalytic performance. Typically, heterojunction structure construction, noble metal loading, and cocatalyst binding have been explored to improve the photocatalytic performance of silver (meta)vanadate by enhancing stability, accelerating charge separation and transportation, prolonging the lifetime of charge carriers and increasing light absorption. Therefore, this review provided insights into the recent progress in the development of efficient modified silver (meta)vanadate and their application in photocatalytic degradation of pollutant, water splitting, and bacteria disinfection. Meanwhile, this review summarized the synthetic methods commonly used in silver (meta)vanadate synthesis. Moreover, as the photocatalytic activity is structure-dependent, the relationship between morphology and photocatalytic property of silver (meta)vanadate was discussed in this review. Finally, the current challenges and the crucial issues of modified silver (meta)vanadate that are in urgent need of being addressed in future research are presented. It is expected that this review could provide meaningful knowledge to help rationally design and fabricate highly-efficient silver (meta)vanadate-based photocatalysts.

作为一种迷人的可见光驱动光催化剂，钒酸银具有窄的带隙，良好的结晶性和易于制备的优点，一直是光催化领域的热点。通常，原始钒酸钒受到光腐蚀，光生e ^-- h ^+的复合率高。对，量子产率差和对太阳光的吸收不足，导致光催化性能差。通常，已经研究了异质结结构的构造，贵金属负载和助催化剂结合，以通过增强稳定性，加速电荷分离和运输，延长电荷载流子的寿命并增加光吸收来改善钒酸银的光催化性能。因此，本综述提供了对高效改性钒酸银开发及其在污染物的光催化降解，水分解和细菌消毒中应用的最新进展的真知灼见。同时，本综述总结了钒酸钒银合成中常用的合成方法。此外，由于光催化活性取决于结构，本文探讨了钒酸银的形貌与光催化性能之间的关系。最后，介绍了在未来的研究中迫切需要解决的改性钒酸银的当前挑战和关键问题。预期该评论将提供有意义的知识，以帮助合理设计和制造高效的（钒）钒酸银基光催化剂。
