Here; a strategy for decomposing gaseous organic contaminants by photocatalytic reactions is reported. A photocatalytic reactor is designed; based on an open tubular reactor with a UV light source installed at the center of the glass tube to permit the vertical irradiation of light onto the photocatalyst. TiO2 immobilized on a stainless steel plate and a fiber based material; respectively; are placed on the inner wall of an open tubular reactor. The fibers of felt induce wake and eddy flow near the inner surface of the reactor; resulting in compression of boundary layer. The compressed boundary layer provides a higher probability of contact between organic contaminants and the photocatalyst; consequently resulting in the enhanced photocatalytic oxidative decomposition of organic compounds. The inlet of photoreactor is modified in order to better control the bulk stream to form spiral-like flow. The reactor with a single tangent inlet exhibits the highest photocatalytic performance among the reactors examined; as an evidence of the improved probability of contact. Importantly; the reactor with a single tangent inlet; in which TiO2 immobilized felt is installed; maintains its photocatalytic activities for as long as twenty days. © 2012 Elsevier B.V;
