TiO 2 loaded on activated carbon fibers (ACF) was performed by using epoxy resin as the precursor of the link between them, followed by calcination at 460°C in N 2 atmosphere, and the changes in surface characteristics and photocatalytic activity after UV irradiation were investigated in detail. After UV irradiation, the pore structure and surface morphology of TiO 2-loaded ACF ( TiO 2/ ACF ) kept unchanged. The UV-Vis spectrum shifted toward shorter wavelengths than that before UV irradiation. XPS results showed that the hydroxyl and C – O groups increased, resulting in an increase in hydrophilicity of TiO 2/ ACF . All these changes caused the increased photocatalytic activity for methylene blue, and the activity was maintained without any decrease when it was used repeatedly. Even at the sixth cycle, its amount of MB removal was still slightly higher than suspended P25.
