This paper on the synthesis of ZnOBiOBR functional cotton fabrics with antimicrobial and photocatalytic properties by researchers from Wuhan University of Engineering and others was published in the important journal Carbohydrate Polymers.

In recent years, the research work of microwave chemical instrument used in the synthesis of materials has become a hot direction of scientific research, which has been paid great attention to by many scholars！

ZnO coated fabrics have attracted wide attention due to their antibacterial and photocatalytic self-cleaning properties. However, the light response of ZnO is limited to the ultraviolet region, which limits its application. In this paper, ZnO/BiOBR functional cotton fabric was synthesized by simple and time saving ultrasonic and microwave method.

Compared with ZnO coated fabric, the photocatalytic activity of ZnO/BiOBr coated fabric under visible light irradiation was obviously improved, but the antibacterial activity of ZnO/BiOBr coated fabric was not affected. At the same time, it also shows good anti-bacterial adhesion and photocorrosion performance.

The introduction of two-dimensional BiOBr nanoparticles not only enhances the absorption of visible light, but also reduces the recombination rate of electron hole pairs. Therefore, the photocatalytic self-cleaning properties of coated fabrics under visible light irradiation were improved significantly. ZnO/BiOBR coated cotton fabrics had the dual functions of antibacterial and self-cleaning, and had broad application prospects in textile, medicine, chemical industry and other fields.

ZnO/ BiOBr coated cotton fabric was successfully synthesized by the ultrasonic-microwave composite method. The results of SEM and TEM show that the ZnO nanoparticles of 12. 1nm are deposited on the BiOBr nanoparticles. The composite has many advantages in the aspects of antibacterial activity and photocatalytic self-cleaning performance. In the aspect of the antibacterial activity, the loading of the ZnO nanoparticles is small, so that the ZnO/ BiOBr coating fabric has the antibacterial activity corresponding to the ZnO coating fabric.

In this paper, multipurpose fabrics with high antibacterial activity and photocatalytic activity are provided.

Reaction mixture and pretreated cotton fabric were poured into ultrasonic microwave reactor (XH-300A, Beijing Xiangghu Technology Development Co., Ltd). The reaction was carried out at 85 ℃ under microwave (2450 MHz,500 W) and discontinuous ultrasound (50% efficiency of 25 kHz,800 W, 2 s interference and 1 s interruption).
