| Abstract | Abstract TiO 2 and Ag-TiO 2 (0.05, 0.25 and 1 wt% of Ag) thin films were prepared by the sol–gel method. The prepared films were characterized using SEM-EDAX, XRD, Raman spectroscopy, atomic force microscopy and UV–Vis spectrometry. Photocatalytic decomposition of N 2 O was performed in an annular batch reactor illuminated with an 8 W Hg lamp (254 nm wavelength). The photoreactivity of Ag-TiO 2 increases with the Ag amount to 0.25 wt% Ag. Further increase of Ag loading to 1 wt% Ag did not change N 2 O conversion. The Ag particles deposited on the TiO 2 surface can act as electron–hole separation centers. The presence of water vapor and oxygen in the reaction mixture slightly improved N 2 O conversion. |
