The optical properties of suspensions of P25 TiO2 photocatalyst are calculated with particulate-aggregates-based light scattering model. The effects of structure, number of monomer, and particle radius of cluster on the absorption and scattering coefficients are analyzed. It is found that the radius of particle in clusters significantly affects their scattering capacity, and this effect could be attributed to the dielectric resonance of single particle and the cooperative scattering caused by coupling of electric dipoles of adjacent particles. Our work may promote the understanding of interaction between light and photocatalysts.
