A study on photocatalytic degradation of acetaldehyde was carried out by using the immobilized TiO₂on a porous α-Al₂O₃tube. TiO₂was immobilized by sol-gel method or suspension coating method. The photocatalyst prepared by the suspension coating method showed the highest reactivity toward photocatalytic decomposition of acetaldehyde. Effective thickness of TiO₂ layer was estimated to be about l0 ㎛. Both O₂and H₂O could initiate the photooxidation. O₂showed promotional effect on the photocatalytic oxidation, which H₂O exhibited inhibition effect. The photocatalytic oxidation of acetaldehyde rate decreased with increasing initial concentration and showed first order expression. In the range of 25-70 ℃, photodecomposition of acetaldehyde was not affected by the temperature.
