KIT-6分子筛负载TiO2对罗丹明B光催化降解性能研究
Photocatalytic Degradation of Rhodamine B Using Supported TiO2 Photocatalyst by Molecular Sieves of KIT-6
摘要
Abstract
TiO2/KIT-6 composites with various titania content were prepared via the sol-gel method.TiO2/ KIT-6 composites were characterized by X-ray diffraction(XRD),N2 adsorption,TEM,FT-IR.The titania crystalline phase was anatase.The BET surface area and pore volume of the composites decreased with the increase of titania content.The average crystal size of these titania particles increased as the titania content increased.The photocatalytic activities of TiO2 /KIT-6 composites which were different TiO2 loading and repeated usage were studied by the photocatalytic degradation of Rhodamine B.The degradation of Rhodamine B followed first-order reaction kinetics.The 30% TiO2/KIT-6 which was baked at 550 ℃ had the best degradation effect, the best degeneration rate of Rhodamine B is 94.5% under optimal conditions: adding 0.0lg TiO2/KIT-6 composites into 70 mL of the 20 mg/L Rhodamine B which reacted for 25 min.关键词
