Degradation of Blue Ink Solution by Silver Chloride Photocatalyst
Main Article Content
Abstract
AgCl was synthesized by the ion-exchange reaction with some metallic Ag nanoparticles on its surface. Its size was in the range 1-2 μm. The XRD diffraction patterns matched with the cubic phase of AgCl crystal with some weak diffraction peaks of metallic Ag. Ag nanoparticles were also detected by scanning electron microscope (SEM). The product showed high photocatalytic degradation efficiency for orange G dye and blue ink solution under UV light irradiation. AgCl crystals prepared with different conditions had no metallic Ag nanoparticles on the surface and showed lower photocatalytic activity.
