Toluene is one of the most emitted VOCs in the industry due to its heavy use as a solvent for the production of paints, thinner and glues. Catalytic oxidation appears a promising method to decompose toluene into CO2 and H2O. Mesoporous cerium oxides were synthesized by using Colloidal Solution Combustion Synthesis (CSCS) methods. Pore size and pore volume of cerium oxides were controlled by varying size of SiO2 nanoparticles. The effect of pore size and pore volume on the catalytic oxidation of toluene was tested. Prepared mesoporous cerium oxides were characterized by X-ray diffraction (XRD), Thermogravity analysis (TGA), scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET). |
