Photoactivity test of Pt-doped
and pure TiO2 nanoparticles
The decomposition of methylene blue (C16H18N3S, MB) solution is used to study the photoactivity of TiO2 nanoparticles, with and without Pt-doping. Under UV light irradiation, the MB solution reacts with test photocatalyst to form colorless liquid. From the decrease of MB concentration with irradiation time, the photocatalytic activity of test powder can be evaluated. Pt doping on TiO2 nanoparitlces is through ALD method. When the ALD process and situation is different, the Pt improvement effect to TiO2 photoactivity is different. |
