Preparation and Self-cleaning Property of Mesoporous SiO2/Bi2O3/TiO2 Multilayered Thin Films
摘要
Abstract
Mesoporous SiO2/Bi2O3/TiO2 multilayered thin films were prepared on glass slides using a solgel/spin-coating method.XRD,UV-Vis and contact angle measurements were used to characterize the structure,transparency and superhydrophilicity of the multilayered thin films.It was found that Mesoporous SiO2/Bi2O3/TiO2 multilayered thin films kept the mesoporous structure of SiO2,performing superhydrophilicity in the dark.The superhydrophilicity of the multilayered thin films coated stearic acid was restored under UV irradiation,showing a good self-cleaning property.Furthermore,mesoporous SiO2/Bi2O3/TiO2 multilayered thin films had a better photocatalytic activity than SiO2/TiO2 and SiO2/Bi2O3 double-layered thin films.关键词
