One-dimensional (1D) nanoparticulates of titanium dioxide (TiO2) and titanate synthesized by wet-chemistry approaches are new advanced materials of unusual properties. This project will investigate the formation and phase transition mechanism of these 1D particulates by various techniques. With such knowledge, we can effectively control the morphology on a scale of nanometers, and tailor the energy gap of these materials. This will significantly influence the photosemiconductive photocatalytic and lithium ions insertion behaviours of the particles so that advanced materials for solar energy conversion, photocatalysts for decomposing organic pollutants in environment, eletrode materials of lithium batteries can be developed.
