Abstract: The UV shielding property of TiO2 pigments was investigated via the photodecomposition of hydrogen peroxide in aqueous medium. Based on the oxygen evolution kinetics, a series of pigments can show different UV shielding properties directly and effectively under UV irradiation(mainly 365 nm). This method is simple, fast and reproducible, and it may have potential applications in industrial production and practical useage.

Key words: TiO2 pigment, hydrogen peroxide, kinetics, UV shielding
