Noble metal doped TiO2has been emerged as an effective catalyst for improving the activity of TiO
2
. Here we report the
preparation of silver doped TiO2by photodeposition process. TiO2and Ag-TiO2
were characterized by X-ray diffraction, scanning
electron microscopy, energy dispersive X-ray spectroscopy, tunnelling electron microscopy, Brunner Emmer Teller analysis. The
average particle size of prepared TiO2 and Ag-TiO2was found to be 7 nm and 20 nm respectively as measured by TEM analysis. BET
surface area of prepared TiO2 and Ag-TiO2 was found to be 150 m
2
/g and 140 m
2
/g, respectively. From the UV-visible measurement,
the absorption in the visible light of the Ag-TiO
2and as prepared TiO2 was found to be improved and was shifted to longer wavelength
(visible range). The obtained results show that the photocatalytic efficiency of Ag-TiO2was better than prepared TiO2
for the
photodegradation of methyl orange.
