    Abstract:

    In this paper, data concerning the effect of pH towards the synthesis of dispersed Ag-TiO2 nanoparticles is reported. TiO2 nanoparticles prepared by sol gel method were coated with Ag by photo deposition under UV light. UV-Vis absorption spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD) and N2 adsorption/desorption method at liquid nitrogen temperature (-196 C) from Brunauer–Emmett–Teller equation (BET) measurements were used to characterize the as-prepared nanocomposite particles. Ag loading of 1.25 wt% on TiO2 was achieved at different pH values ranging from 1 to 10. TEM micrographs revealed that Ag-coated TiO2 nanoparticles showed a higher degree of agglomeration at alkaline pH values. The diameter of the titania particles were in the range of 2 to 11 nm as deduced from XRD and confirmed by microscopy. A maxima in the BET surface area was achieved for the Ag-TiO2 nanoparticles at a pH of 5. Some important applications of the nanoocomposite materials will be presented.
