TiO2 nanoparticles have long been utilized in various industrial application (e.g. semiconductiors ,photocatalyst, optical coating) due to its photonic band structure. [1,2] Especially TiO2 nanoparticle complex can be utilized in sun care products because of its UV-ray shielding (or absorbing) performance and low absorption in the visible region. In the present work, we synthesized mesoporous TiO2 sphere with a crystalline framework and a high surface area. In order to enhance the UV light blocking ability, various materials (e.g. Tinosorb) were loaded within the mesoporous of TiO2 materials. The physicochemical properties of TiO2 based composite materials thus obtained have been investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and nitrogen adsorption-desorption isotherm, and UV-visible spectroscopy. UV-blocking materials loaded on mesoporous TiO2 materials exhibit higher UV-light blocking effects than the TiO2 maerials without other metal oxides, which is probably due to increase in reflective index and enhanced of UV-Vis absorption ability.
