环境水中氯酚类污染物对人类的健康和生态环境有巨大的危害，因此对氯酚类污染物的去除和监测及其重要。针对如何实现构建对水体中氯酚类污染物的同时可见光光催化降解和电化学监测平台的关键科学问题，本项目拟采用精确设计多能纳米材料的思路，通过气固生长、化学水热、电化学沉积、磁控溅射、阳极氧化、阳极剥离等方法，在导电基体上大面积制备出包含C、Au和TiO2三种材料的功能复合纳米阵列，研究其形貌、组成、微观结构与其光催化和电化学分析性能之前的关系，首次提出并研制出具备对氯酚类污染物同时高效可见光光催化降解和精准电化学实时监测为一体的多功能平台。为发展对水体中有机污染物的同时去除和痕量在线监测提供实验依据和理论基础，为环境监测和治理提供新思路、方法和平台。

Chlorophenols (CPs) are a major group of pollutants of health and environmental concern because of their high toxicities and wide existence in water. Therefore, it is of great significance to develop effective methods for removal and monitoring of CPs. Fabrication of C, Au, and TiO2 integrated functional nanoarrays on conductive substrates, which have not only excellent photocatalytic activities for degradation of CPs but also outstanding electrochemical activities for determination of CPs, is proposed for the first time in this project. The nanoarrays compose of highly photocatalytic species like TiO2 and highly electroactive materials including carbon nanomaterials and Au nanoparticles. The composites will be prepared by using gas-solid, hydrothermal, electrodeposition, magnetron sputtering, anodization, and anodic exfoliation methods. The influence of nanoarrays’ morphology, chemical composition, microstructure on the photocatalytic degradation and electrochemical performance toward CPs will be systematically investigated. The overall execution of this project will provide a set of systematic theory, technique, and a new way for simultaneous photocatalytic removal and online electrochemical monitoring of CPs and other organic pollutants in water and real samples.
