Abstract

Due to the widespread use of medicine in recent years, antibiotics as the emerging pollutants have been widely detected in the aquatic environment. To address this situation, developing advanced treatment technologies to effectively remove antibiotics are emergently needed. Photocatalysis for the removal of antibiotics driven by sunlight has been considered a promising technology, due to its green, environmentally friendly, and cost-effective properties. Currently, great efforts have been done to construct highly efficient photocatalytic oxidation systems for the degradation of antibiotic pollutants. To be updated, we herein summary the recent progress on the removal of antibiotic pollutants using the photocatalytic oxidation process within the last 5 years. We begin by introducing the classification, structures, and environmental hazards of common antibiotics. Subsequently, the fundamental mechanism of photocatalytic degradation of antibiotics is presented and the details on the degradation information of the different kinds of antibiotics via semiconductors photocatalysts are discussed and listed. Finally, we present a brief discussion on the opportunities and challenges remaining in photocatalytic removal of antibiotic pollutants.

摘要

由于近年来药物的广泛使用，抗生素作为新兴污染物在水环境中被广泛检测到。为了解决这种情况，迫切需要开发先进的治疗技术来有效去除抗生素。由阳光驱动的光催化去除抗生素被认为是一项很有前途的技术，因为它具有绿色、环保和具有成本效益的特性。目前，人们已经做出了巨大的努力来构建高效的光催化氧化系统来降解抗生素污染物。为了更新，我们在此总结了过去 5 年内使用光催化氧化工艺去除抗生素污染物的最新进展。我们首先介绍分类、结构、常见抗生素的环境危害。随后，介绍了光催化降解抗生素的基本机理，并详细讨论并列出了不同种类抗生素通过半导体光催化剂降解的信息。最后，我们简要讨论了光催化去除抗生素污染物的机遇和挑战。
