SYNTHESIS OF A NANO-STRUCTURED TITANIA SURFACE AND ITS APPLICATION IN PHOTOCATALYTIC OXIDATION FOR WATER TREATMENT

澳大利亚正面临严重的淡水危机。尽管公众对节约和高效利用水的意识越来越高，但水/废水的再利用一直被忽视。在澳大利亚，97%的城市径流和86%的污水是非生产性的。如何回收和再利用这些垃圾成为一个紧迫的问题。本项目试图开发新型二氧化钛基光催化剂，将有机污染的水转化为可重复使用/饮用的淡水。该项目的创新之处在于合成了固定形式的高活性纳米结构二氧化钛表面，以解决下游分离问题。这种光催化剂的成功开发将给澳大利亚带来显著的环境和社会经济效益。

Australia is facing severe freshwater crisis. Although there is an increasing public awareness of saving and using water efficiently, re-using water/wastewater has been neglected. In Australia, 97% of city runoff and 86% of effluent water is unproductive. How to recycle and re-use them becomes an urgent issue. This project attempts to develop novel titania based photocatalysts to convert organic contaminated water into reusable/potable freshwater. The project's innovation lies in the synthesis of highly reactive nano-structured titania surfaces in fixed form to solve downstream separation problem. Successful development of such photocatalysts will show significant environmental and socio-economic benefits to Australia.
