摘要:

四环素是一种常用的广谱抑菌剂。其在人体和动物体内代谢不完全,可释放到环境中。近年来,四环素在水环境及土壤中均有检出,其污染问题逐渐引起人们的关注。光催化法是高效去除抗生素的方法之一。而常用的TiO2光催化剂具有光响应范围较窄,电子-空穴对易复合等缺陷。采用铋基光催化材料去除水体中的四环素,具有稳定性高、载流子密度低、平均自由程长等性能。总结了铋基光催化材料的种类、改进方法及降解四环素的关键操作参数(pH、四环素浓度、催化剂投加量、光强),总结了反应机理和常见的光催化中间产物,并对铋基光催化剂未来的研究方向进行展望。

Abstract:

Tetracycline(TC) is a widely used bacteriostatic agent. Its metabolism in human and animal body is not complete, can be released into the environment. In recent years, TC has been detected in water environment and soil, and its pollution has gradually attracted people's attention. Photocatalysis is one of the most effective methods to remove antibiotics. The commonly used TIO2 has some defects, such as narrow photoresponse range and easy recombination of electron-hole pair. Bismuthal photocatalysts could be used in the TC degradation in water, which had the advantages of high stability, low carrier density, and long average free path. The types and improvements of bismuthal photocatalysts were summarized. The key parameters, such as pH, TC concentration, catalyst dosage, and light intensity on TC degradation were discussed. The reaction mechanisms and the common intermediate products of TC degradation were listed. Finally, the future research direction of bismuthal photocatalyst was proposed.

Key words: bismuthal materials, photocatalysis, tetracycline
