Abstract

Based on the study of equilibrium adsorption on viscose rayon-based activated carbon fiber (ACF) by gravimetric method, mounting of TiO₂ on PAN-based activated carbon cloth (ACC) and their photocatalytic activity as well as adsorption performance for benzene were investigated. The crystallinity of TiO₂ and pore structure were characterized by XRD and N₂ adsorption. The results show that crystallinity of TiO₂ and pore structure could be postulated by heat treatment condition. Both crystallinity of TiO₂ and pore structure of hybrid have effects on photocatalytic performance of TiO₂-mounted ACC. It would be more attractive and prospective for the combination of TiO₂ photocatalytic activity and adsorption ability of porous materials.
