The removal, of volatile organic compounds by adsorption and photocatalytic oxydation

It is important to remove volatile organic compounds (VOCs) emitted frequently from daily activities because they may endanger human's health. In this work, based on the study of equilibrium adsorption on viscose rayon-based activated carbon fiber (ACF) by gravimetric method, mounting of TiO(2) on PAN-based activated carbon cloth (ACC) and their photocatalytic activity as well as adsorption performance for benzene were investigated. The crystallinity of TiO(2) and pore structure was characterized by XRD and N(2) adsorption. The results showed that crystallinity of TiO(2) and pore structure could be postulated by treatment condition. Both crystallinity of TiO(2) and pore structure of hybrid have effects on photocatalytic performance of TiO(2)-mounted ACC. It would be more attractive and prospective that combination of TiO(2) photocatalytic activity and adsorption ability of porous materials.
