Thermally treated particles were characterized by XRD and EXAFS. Particles with 5 wt% Mn content showed the most dispersed Mn components in the supported TiO2 with the lowest crystallinity. BET and HR-TEM showed that their surface area and pore volume increased to 299.5 m(2) g(-1) and 0.329 cm(3) g(-1), respectively. TPR and XPS showed these particles to have higher oxygen mobility and redox properties than commercial P25 similarly prepared and loaded with 5 wt% Mn2O3. They also had greater amounts of Mn3+ groups on their surfaces. 5 wt% manganese loaded TiO2 particles fabricated by CVC and impregnation are expected to have broad applicability.
