光催化剂BiVO4的研究进展

Research Progress of Photocatalyst BiVO4

能源危机和环境恶化日趋严重,人们的环保意识逐渐增加。而碍于技术的匮乏,如何解决这两大难题以成为我国持续发展战略的首要任务。光催化因其效率高,安全环保,无二次污染的特点,为处理环境问题提供有效的办法。其中,钒酸铋(BiVO4)由于具有较窄的带隙能(2.4eV),对紫光和可见光都能产生响应,表现出较好的光催化活性。本文概述了光催化剂的机理,以及光催化BiVO4的研究进展。

The energy crisis and environmental degradation are becoming more and more serious, and people's awareness of environmental protection is gradually increasing. Due to the lack of technology, how to solve these two problems has become the primary task of China's sustainable development strategy. Photocatalysis provides an effective method for dealing with environmental problems because of its high efficiency, safety and environmental protection, and no secondary pollution. Among them, bismuth vanadate (BiVO4) has a narrow band gap energy (2.4 eV), which can respond to both violet and visible light, and exhibits good photocatalytic activity. This paper outlines the mechanism of photocatalysts and the research progress of photocatalytic BiVO4.
