Bismuth vanadate (BiVO4) is a promising visible-light driven semiconductor photocatalyst with various benefits such as low production cost, low toxicity, high photostability, resistance to photo-corrosion and narrow band gap with a good response to visible-light excite. However, the fast recombination of photoinduced charge carriers restricts their photocatalytic activity. In the past decades, many attempts were adopted to enhance the photocatalytic activity of BiVO4. Significant advances in understanding the fundamental issues and the development of an efficient photocatalyst have been made in current years. In this review, we have provided a comprehensive overview of the latest progress on the morphology control and growth mechanism of BiVO4 micro/nano-structures, doping with metal and non-metal elements and semiconductor coupling along with some highlights in the photodegradation of organic pollutants under visible-light illumination. This review may benefit the researchers and engineers in the arena of material chemistry for designing new BiVO4 based photocatalysts with low production cost and high efficiency.

BiVO 4光催化剂的综述:太阳能光催化应用中的活性增强方法

钒酸铋(BiVO 4)是一种有前途的可见光驱动半导体光催化剂,具有多种优点,例如生产成本低,毒性低,光稳定性高,耐光腐蚀和窄带隙,并对可见光激发具有良好的响应。然而,光诱导的载流子的快速重组限制了它们的光催化活性。在过去的几十年中,进行了许多尝试来增强BiVO 4的光催化活性。近年来,在理解基本问题和开发有效的光催化剂方面取得了重大进展。在这篇综述中,我们提供了BiVO 4形态控制和生长机制的最新进展的全面概述。微/纳米结构,掺杂金属和非金属元素以及半导体耦合以及可见光照射下有机污染物的光降解中的一些亮点。这项审查可能有益于材料化学领域的研究人员和工程师设计出生产成本低,效率高的新型基于BiVO 4的光催化剂。
