Effect of doping parameters on photocatalytic degradation of methylene blue using Ag doped ZnO nanocatalyst

The aim of this study is the synthesis, characterization and photocatalytic degradation of ZnO and Ag doped ZnO nanocatalysts of various compositions synthesized by using co-precipitation method. The nanocatalysts were annealed at the 723.15 K temperature. The obtained nanocatalysts were characterized in concerns their crystalline structure using X-ray diffraction, morphology using scanning electron microscopy (SEM) and electron dispersive X-ray spectroscopy (EDS) in concern with their composition. Photocatalytic activity of nanocatalyst was tested by applying it for photocatalytic degradation of Methylene Blue under different experimental conditions. The photocatalytic activity found to increase with the increase of dopant concentration.
