Preparation and Photocatalytic Activity under Visible Light Irradiation of Crystalline Mesoporous Titania Particles
Crystalline mesoporous titania particles were prepared and their photocatalytic activity under visible light irradiation was investigated. A novel method including a low-temperature crystallization technique of titania in the presence of cationic surfactants supplied mesoporous titania particles having crystalline walls. The obtained titania showed an absorption threshold drastically shifted to the longer wavelength side and a photocatalytic activity under visible light (>440 nm) irradiation.
