Photocatalytic Degradation of Toluene over Titanium Diozide Thin Film
An experimental study on VOCs removal with photocatalyst in a batch reactor was carried out at atmospheric pressure and room temperature. TiO2 thin film photocatalyst coated on glass spring was prepared with dip-coating method. The photocatalyst was extensively characterized by means of spectroscopy (XRD) and microscopy (SEM). Toluene was taken as the typical VOCs for photocatalytic degradation as a function of gas flow rate and single versus mixed gases. The study indicated that flow rate influenced the degradation significantly and there were the optimal values; the difference between single gas and the mixed gas was remarkable and the degradation rate of mixed toluene in VOCs were higher than single toluene. Mechanism of titania-assisted photocatalytic degradation of toluene was also investigated in the paper, toluene molecule was turned into CO2 and H2O in the end.
