摘要

摘要采用基于粒子聚集体的光散射模型计算了P25 TiO2光催化剂悬浮液的光学性质。分析了结构、单体数目、团簇粒子半径等因素对吸收散射系数的影响。发现团簇中粒子半径对其散射能力有显著影响，这种影响可归因于单个粒子的介电共振和相邻粒子电偶极子耦合引起的协同散射。我们的工作可能促进对光与光催化剂相互作用的理解。

Numerical investigation on the optical properties of TiO2 photocatalyst suspension by light scattering model of particulate aggregates

Abstract. 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.
