Development of visible light activated photocatalysts for the inactivation of microorganisms and degradation of organic compounds

- Improving photocatalytic efficiency of TiO2 through facet control

- Enhanced disinfection of microorganisms and effective decomposition of recalcitrant organic pollutants

Assessing the formation and the properties of high-valent metal species.

-Understanding the formation chemistry of various high-valent metal species

-Establishing the relationship between chelation of ligand compounds with the metal centre and the reactivity of corresponding high-valent metal species with the chelated compounds or other substrates in bulk

-Developing next-generation advanced oxidation process utilising high-valent metal species that can minimise unnecessary energy and chemical consumption.
