| 摘 要： | 近年来，新污染物在水体中被频繁检出，其化学性质稳定、易生物积累，给生态环境和人类健康带来严重威胁. 为解决此问题，高级氧化技术逐渐发展为一种有前景的环境修复方法，在众多氧化剂中，分子氧(O2)是丰富、经济、绿色的氧化剂. O2主要经由催化促进的电子转移和能量转移途径而被活化，进而转化为活性氧物种(ROS). 活化O2转化为ROS，有望成为清除水中新污染物富有潜力的研究方法和实用技术. 目前，研发更高效催化材料(或其他类型活化材料)，以实现对O2的高效活化和对污染物的彻底、快速降解是相关领域研究的关注焦点. 本文重点介绍了活化O2降解水中新污染物的基本概念和最新研究进展，包括O2可转化生成的主要ROS、O2活化策略、活化O2用于降解新污染物的研究成果等，并对O2活化所遇到的核心问题和未来发展趋势进行了总结和展望.

| Abstract: | In recent years, emerging contaminants (ECs) have been frequently detected in waters. ECs are chemically stable and easily bioaccumulative, thus seriously threaten the ecological environment and human health. To alleviate this problem, advanced oxidation process has been gradually developed into a promising remediation strategy. Among various oxidants, molecular oxygen is considered to be an abundant, economic and green oxidant. Molecular oxygen can be mainly activated into reactive oxygen species through catalytic electrons or energy transfer, which is expected to become a potential technology for removing emerging persistent contaminants in water. Currently, the research and development of more efficient catalytic materials (or other activation materials) for activating the molecular oxygen thoroughly and rapidly to degrade the ECs is the central goal of researchers. It mainly focuses on the basic concepts and latest progresses of molecular oxygen activation for degradation of ECs in water, including the main active oxygen species generated from molecular oxygen, the state-of-art activation strategy of molecular oxygen, examples of efficiently activation of molecular oxygen and degradation of ECs etc. Finally, the crucial problems and future development of molecular oxygen activation are summarized and prospected. |
