Green synthesis of three-component Ag/AgCl/TiO2 nanocomposite using Zataria Multiflora plant

Green synthesis plays an important role because of its involvement in unusual syntheses of metal nanoparticles from plant extracts, which have antimicrobial potential. Therefore, green synthesis of nanoparticles from plant extracts is a suitable way to produce nanoparticles. Therefore, the aim of this research was to synthesize Ag/AgCl /TiO2 three-component nanocomposite using Zataria Multiflora plant and evaluate the size and morphology of the produced nanoparticles. For this purpose, synthesis, and characterization of Ag/AgCl/TiO2, a three-component nanocomposite was done using Zataria Multiflora plant extract using UV-Vis, XRD, TEM, and FTIR techniques. Then, the characteristics of nanocomposites were investigated. The results showed that the largest diameter of the non-growth halo was observed in all studied bacteria in the nanocomposite containing 50% color and in the nanocomposite containing 5% (Ag/TiO2mol). The diameter of the non-growth halo increased from 0.5% to 3% in the film containing TiO2/Ag/AgCl nanoparticles in all investigated microorganisms. Also, TEM images showed the uniform loading of Ag/AgCl nanoparticles on the TiO2 surface. Overall, the obtained results showed that Zataria Multiflora plant extract, along with silver and titanium dioxide nanocomposites, has a high potential in producing nanoparticles with high purity, in nanometer sizes, with antimicrobial properties, which has properties in the food industry as a coating and film.
