Australia is one of the driest continents and re-use of water/wastewater has been an urgent issue. Photoelectrocatalytic oxidation processes based on nanostructured TiO2 electrode are able to mineralize common aquatic organic and microbial pollutants. The proposed technology has the advantages of strong oxidation power and cheap production cost, and it is chemically stable, robust under UV illumination, and most importantly, environmentally friendly. The success of the project can place Australia in a leading position of developing cutting-edge TiO2 nano-material-based photoelectrochemical technologies for environmental wastewater treatment and drinking water disinfection.
