Abstract
Photocatalytic oxidation technology is a promising green technology for degrading volatile organic compounds (VOCs) due to its non-toxic, environmentally friendly, energy-saving, and affordable characteristics. In this paper, Ag/TiO2@PANI-MC with high stability and activity was synthesized by the mechanochemical method. The designed Ag/TiO2@PANI-MC were of high specific surface area, light absorption capacity and low recombination rate of electron–hole pairs, which was demonstrated by various characterizations. When applied in photocatalytic toluene oxidation, the conversion is 17% at 20 °C under 100 W high-pressure mercury lamp. This photocatalytic performance is with less temperature sensitivity, and significantly improved compared with Ag/TiO2 or TiO2 catalysts. Furthermore, the reaction routine was also confirmed by GC-MS and the toluene was mineralized to CO2. More importantly, the Ag/TiO2@PANI-MC indicated good reusability after 3 cycles, which was verified by the FT-IR comparison of fresh and used catalysts. Our work proves a potential way on constructing nanocomposite based on mechanochemical synthesis for enhanced toluene photocatalytic degradation.
