Abstract
TiO 2 particulate photocatalyst anchored on activated carbon fibers (ACFs) was prepared by a molecular adsorption-deposition method. The TiO 2 particles deposited on the carbon fibers formed a coating of about 100 nm in thickness. The photocatalyst prepared was characterized by means of SEM, EDS, XRD and UV-vis adsorption spectroscopy. Anatase-type TiO 2 was uniquely developed, and the micrographic structure of ACFs was not damaged during preparation. The roomy space between adjacent carbon fibers could allow UV-light to penetrate into the felt-form photocatalyst to a certain depth, so that a three dimensional environment was formed for the photocatalytic reaction. Such TiO 2/ACFs photocatalyst exhibited its photocatalytic reactivity in photodegradation of concentrated methylene blue (MB) solutions. The MB molecules in the bulk solutions was supposed to be condensed around TiO 2 particles by adsorption by ACFs. Therefore, the photocatalyst possesses the combined effect of adsorption by activated carbon fibers and photocatalytic reactivity of anatase-type TiO 2 on MB photodegradation.
