| Abstract: | Review on the relation between calcination temperature and structural properties of TiO2 with aspects to the composition of phase, density of lattice defects, contents of surface hydroxyl, size of crystal particles and special surface area were presented. It also discussed some processes which influence the photocatalytic activity, such as two-phase ef- feet, transportation/trap of carriers and size quantum effect. Furthermore, photocatalytic removal of representative organic pollutant in water and relevant characteristics of catalyst were summarized. |
