Preparation of Ti-doped BiOCl nanosheets and its piezoelectric photocatalytic performance

doi:10.19965/j.cnki.iwt.2022-0614

Abstract

Abstract:

The Ti doped BiOCl nanosheets were prepared by a one-step hydrothermal method. XRD，SEM，PFM and other analytical techniques were used to characterize the crystal structure and morphology of the prepared sample. With tetracycline（TC） as the target pollutant，the piezoelectric photocatalytic performance of Ti-BiOCl was studied under simulated sunlight and ultrasound. The results showed that BiOCl nanosheets exhibited roselike sheet with a thickness of about 25-250 nm and had good crystal structure and high piezoelectric response ability. With the action of light（300 W） and ultrasonic（100 W，45 kHz），the removal rate of TC by Ti-BiOCl reached 94.67% within 20 min. The first-order reaction rate at the room temperature was 0.168 min^-1，which was significantly better than photocatalytic or piezoelectric catalytic processes alone.

Key words: Ti-BiOCl nanosheets, piezoelectric photocatalysis, tetracycline

摘要：

采用一步水热法制备了Ti掺杂的BiOCl纳米片，并利用XRD、SEM和PFM以及其他分析测试技术对所制备催化剂的晶体结构和形貌进行测试。以四环素（TC）为目标污染物，在模拟太阳光和超声作用下，研究了Ti-BiOCl的压电光催化性能。结果表明，Ti-BiOCl材料由厚度为25~250 nm的纳米片组成，具有良好的晶体结构和较高的压电响应能力。在光（300 W）和超声（45 kHz，100 W）协同作用下，Ti-BiOCl在20 min内可以去除94.79%的TC。室温下一级反应速率常数达0.168 min^-1，显著优于单独光催化或单独压电催化过程。
