Photoelectrocatalysis-based Techniques for Bactericidal Applications

有效控制供水质量对公众健康至关重要。本项目旨在开发一种基于光电催化(PEC)的新型杀菌技术，能够瞬间灭活和快速分解循环水中的水媒病原体。创新地利用具有紫外线(UV)和可见光活性的半导体光阳极上的PEC工艺，目的是原位产生稳定的二卤化物阴离子、活性氧物种和光孔作为有效的杀菌剂，实现对水性病原体的即时灭活和快速分解。该项目的成功预计将为澳大利亚水务行业提供保护再生水使用的有利技术。

Effective control of the quality of water supply is paramount for public health. This project aims to develop a novel photoelectrocatalysis (PEC) based bactericidal technology capable of instant inactivation and rapid decomposition of waterborne pathogens in recycled water. The PEC processes at the illuminated semiconductor photoanodes with ultraviolet (UV) and visible light activities will be innovatively utilised with the aim of in-situ generation of stable di-halide radical anions, reactive oxygen species and photoholes as effectual bactericides to achieve instant inactivation and rapid decomposition of waterborne pathogens. The success of the project is expected to provide Australian water industry with enabling technology to safeguard recycled water usage.
