TiO2 photocatalysis, one of the most powerful advanced oxidation technologies (AOTs), has a great potential to completely destroy harmful and non-biodegradable organic contaminants in water. The technology has received great attention for environmental remediation due to its effectiveness to generate hydroxyl radicals under UV light irradiation without addition of other chemicals. We have been pioneering so-called TiO2-based advanced oxidation nanotechnologies, including the systematic self-assembling-based synthesis of highly efficient porous TiO2 photocatalysts in the form of particles, films, and membranes. The materials can be also activated under visible light irradiation to utilize sustainable solar energy for environmental remediation. Especially, TiO2 photocatalytic membranes exhibit multifunctional capability such as decomposition of organic chemicals, destruction of biological toxins, disinfection of pathogenic microorganisms, physical separation of contaminants, and anti-biofouling action. In the presentation, we will share our experience on the development of innovative TiO2 materials and their applications to AOTs for water and wastewater treatment.
