“…The diffraction peaks at 2h = 25°corresponds to the (1 0 1) plane of the anatase phase of TiO 2 . The doping of TiO 2 with silver is confirmed by the presence of diffraction peaks around 2h = 38.4°, 44.5°and 64.6°w hich corresponds to the (1 1 1), (2 0 0) and (2 2 0) planes of silver, respectively [45]. The average particle size of the prepared nanoparticles was calculated by using the Scherrer's equation D = 0.9k/bcosh, where 'k' is the wave length of X-ray radiation (0.1540 nm), b is FWHM (full width at half maximum) in radians, h is diffraction angle, and D is particle diameter size [7 (b)].…”
