摘要：
The oxalic acid treated HZSM-5 zeolite was used as support for TiO2 prepared by sol-gel method. Photocatalytic activity of the zeolite and the loaded TiO2 were studied. Decoloration on HZSM-5 under UV irradiation was quite small at even very high HZSM-5 concentrations. Methyl orange can be adsorbed on surface of HZSM-5, and the zeolite can subsequently have minor photocatalytic activity. TiO2 content in the supported TiO2/HZSM-5 is also a key factor influencing photocatalytic activity of the supported TiO2. The TiO2/HZSM-5 containing 60% of TiO2 showed the optimal activity for samples supported on every concentration of oxalic acid. The 0.3 mol/l oxalic acid treated HZSM-5 supported TiO2 has the maximum activity.
