Positive Effect

Silver doped TiO2 nanoparticles have been prepared by liquid impregnation (LI) and photodeposition (PD) methods and characterized by surface analytical methods such as scanning electron micrographs (SEM) and X-ray diffraction (XRD). The photocatalytic activity of silver doped TiO2 was tested by photocatalytic degradation of C.I. Acid Red 88 (AR88) as a model compound from monoazo textile dyes. Results show silver doped TiO2 is more efficient than undoped TiO2 at photocatalytic degradation of AR88. The positive effect of silver on the photoactivity of TiO2 at degradation of AR88 may be explained by its ability to trap electrons. This process reduces the recombination of light generated electron-hole pairs at TiO2 surface. Silver content has an optimum value 2% in LI and 0.5% in PD methods for achieving high photocatalytic activity. The AR88 decomposition with Ag-photodeposited method was much higher than that of deposited with LI method.
