氧化钨基S型异质结光催化领域研究进展

Research Progress of Tungsten Oxide-based S-type Heterojunction Photocatalysis

随着严重的污染问题和能源枯竭问题得到重视,光催化能源技术开始得到研究工作者们的重视。其中基于WO_(3)的金属氧化物光催化剂,拥有优秀的物化性能而得到密切关注。但WO_(3)的电荷载流子的复合率大和导带边缘位置小的缺点限制了WO_(3)光催化性能的进一步提高。但科研工作者们通过构建新型的S型异质结,实现了解放WO_(3)的新路径。因此,本文介绍了WO_(3)基S型异质结的设计理念、表征办法、制备策略。除此之外,还对近期的应用方向进行了总结报告,并对将来的研究方向进行了展望。

As serious pollution issues and energy depletion become a focus,photocatalytic energy technology has begun to attract the attention of researchers.Among them,tungsten oxide(WO_(3))-based metal oxide photocatalysts,with their excellent physicochemical properties,have garnered close attention.However,the high recombination rate of charge carriers and the small position of the conduction band edge in WO_(3) limit further enhancement of its photocatalytic performance.Nevertheless,researchers have constructed a new type of S-shaped heterojunction,paving a new path for the liberation of WO_(3).Therefore,this review introduces the design concept,characterization methods,and preparation strategies for WO_(3)-based S-scheme heterojunctions.In addition,it summarizes recent application directions and provides a prospective look at future research directions.
