Abstract
The kinetics of photocatalytic decomposition of gaseous toluene in our study generally would follow the Langumuir-Hinshelwood (L-H) model. The rate constant k, as fitted by L-H model, for the SG-TiO2-based catalysts is larger than that of P25-TiO2-based catalysts while the absorption constant K, on the contrary, follows the different trend. The higher activity of SG-TiO2 could be attributed to the smaller grain size (4.6-8.1Â nm) of anatase crystals as evaluated in XRD diffraction pattern.
