С. 271-273Abstract: In the present study we performed the synthesis and characterization of ZnO-Ag nanoparticles. ZnOAg nanoparticles were prepared by the electric explosion of two twisted wires in an oxygen-containing atmosphere in three different contains of silver. Photocatalytic activity were study at the Methylene Blue degradation by visible light irradiation. The recycle test was performed for six cycles using the best photocatalyst to confirm the ability of the reuse of the photocatalyst. The antibacterial activity of ZnO-Ag composite nanoparticles was determined by the suspension method under visible light illumination with E.coli ATCC 25922 bacterial strains. The methylene blue degradation efficiency by ZnO-12Ag nanoparticles reached 90 %, which was higher than that of ZnO nanoparticles produced by electric explosion of zinc wire. Composites had high antibacterial activity against E.coli bacteria.
