Abstract: Mn-ZSM-5 series catalysts were synthesized by ion exchange method and were loaded with TiO2 by impregnation. These catalysts were characterized by UV-VIS, X-ray diffraction (XRD), BET, and their ozone-assisted photocatalytic performance was investigated. The results showed that ozone contributed to the photocatalytic degradation of acetaldehyde. Among these catalysts prepared, TiO2/Mn-ZSM-5 exhibited higher catalytic activity on the degradation of acetaldehyde. The improvement was attributed to the synergetic effect among adsorption/concentration and ozonation/catalytic reaction.
Key words: Photodegradation; Ozone; Synergistic effect; Acetaldehyde
