摘要
在WO_(3)晶格中引入氧空位等缺陷,形成非化学计量比的氧化钨(WO_(3-x),是增强WO_(3)光催化活性的一种有效方法。首先综述了氧空位对WO_(3)光催化活性的影响机制,然后探讨了局域表面等离子共振(LSPR)效应及贵金属/含碳材料与氧空位协同效应对其光催化活性的影响,最后对WO_(3-x)在光催化领域应用中存在的挑战进行了展望。
It is an effective way to enhance the photocatalytic activity by fabricating some defects such as oxygen vacancy into WO_(3)lattice to make nonstoichiometric WO_(3-x).This paper firstly describes the mechanism of the effect of oxygen vacancy on the photocatalytic activity of WO_(3),and then,reviews the influence of the localized surface plasmon resonance(LSPR)effect and the synergistic effects of noble metal/carbon containing materials,and oxygen vacancy.Finally,prospectsing and challenging of WO_(3-x)application in the field of photocatalysis are discussed in the end of this work.
