Abstract

A BiO2−x/COF composite was successfully synthesized by simple mechanical ball milling. Compared to pure BiO2−x and COFs, the BiO2−x/COF composite (1 : 9) showed superior photocatalytic capability. Under visible light irradiation for 90 min, the photocatalytic degradation rate of DCF reached 97%. In addition, the characterization results showed that the formation of heterojunctions and the increase in oxygen vacancy concentration were the reasons for the enhancement of the photocatalytic activity. It is confirmed by free radical capture experiments that ˙O2 and h+ are the main reactive substances in the photocatalytic process. The photocatalytic degradation mechanism of the composite and the photocatalytic degradation pathway of diclofenac were deduced.

用于光催化降解双氯芬酸的富氧空位 BiO2-x/COF 异质结
通过简单的机械球磨,成功合成了 BiO2-x/COF 复合材料。与纯 BiO2-x 和 COF 相比,BiO2-x/COF(9:1)具有更优异的光催化能力。在可见光照射 90 分钟后,DCF 的光催化降解率达到 97%。此外,表征结果表明,异质结的形成和氧空位浓度的增加是光催化活性增强的原因。自由基捕获实验证实,-O2- 和 h+ 是光催化过程中的主要活性物质。推导出了复合材料的光催化降解机理和双氯芬酸的光催化降解途径。

期刊介绍: ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
