Abstract：TiO2 composite condensation of p-phenylenediamine and p-phenylenedialdehyde (TiO2@PT) catalysts were prepared by in-situ condensation method, using p-phenylenediamine and p-phenylenedialdehyde as raw materials. The toluene photocatalytic degradation abilities of the catalysts were studied. The catalysts' morphologies and optical properties were characterized by scanning electron microscope (SEM), surface area analysis (BET), fourier transform infrared spectroscopy (FT-IR), photoluminescence spectroscopy (PL) and ultraviolet-visible spectroscopy (UV-Vis) and transient photocurrent (TPC). It was found that under 365nm ultraviolet irradiation, TiO2@PT catalyst had a good degradation ratio on toluene. In addition, the toluene degradation capacities of TiO2@PT with different polymer coating ratios were studied under various catalyst dosages, toluene concentrations, and reaction temperatures. The results showed that the highest degradation conversion was 26.41%, under 100W ultraviolet irradiation (365nm), 0.1g TiO2@1%PT dosage, 1000×10-6toluene concentration, corresponding to a reaction rate of 1177.89μmol/(g·h).
