Femtosecond diffuse reflectance spectroscopy for studying ultrafast photophysical and photochemical processes of optically scattering materials has been developed and applied to photocatalytic TiO<SUB>2</SUB> powders. It is demonstrated that the spectroscopy has the similar spectroscopic and temporal resolutions to those of transmittance mode transient absorption one. Temporal behavior of diffuse reflected light is analysed by extended Kubelka-Munk model and simulated numerically. Excitation energy relaxation processes of TiO<SUB>2</SUB> powders are measured directly in femtosecond to nanosecond time domains, and electron-hole charge separa-tion and recombination dynamics, and charge transfer to adsorbed molecules on TiO<SUB>2</SUB> surface are made clear. The results are discussed in terms of physical and structural properties of TiO<SUB>2</SUB> and environmental conditions.
