负载型二氧化钛催化剂的制备及催化降解苯酚的研究
Photocatalytic Degradation of Phonei by I - TiO2 Supported on Activated Carbon
摘要
Abstract
I-doped TiO2 photocatalysts were fabricated by hydrothermal method,using tetrabutyl titanate as precursor, potassium iedate as doping sources and then I-doped TiO2 photocatalysts were immobilized to granular activated carbon with the mesh number of 20 to 40 ( 0. 9 mm - 0. 45 mm) by soaks-sintering process. The catalysts were characterized by XRD,XPS,EDS. The adsorption efficiency of phenol and the degradation efficiency under simulated sunlight by I -TiO2/AC of different loading times were investigated. The results showed that I-doped TiO2 was successfully immobilized to granular activated carbon, the adsorption efficiency of phenol by I - TiO2/AC reached 95.8% and degradation efficiency of phenol under simulated sunlight by I-TiO2/AC came to 64%.关键词
