Influence of hydrochloric acid concentrations on the formation of AgCl-doped iron oxide-silica coreshell structures

Popis výsledku v původním jazyce

Silver chloride nanoparticles with the average size of about 45nm have successfully been doped onto the iron oxide-silica coreshell surfaces by a simple room temperature wet chemistry method under ambient atmosphere.The Stöber process has been used to make the coreshell structure, followed by adsorption of Ag+ species on silica surface prior to the addition of HCl and polyvinylpyrrolidone.The concentration of HCl acid that was used to induce the growth of AgCl particles was varied from 0.12mM to 12x103mM of concentrations.Results showed that at a very high concentration of HCl, large AgCl agglomerates with irregular cubic-like morphology were obtained while at a very low concentration, AgCl particles having a uniform cubic morphology were observed.Concentrations below 12mM result in irregular and nearly spherical morphology of AgCl particles with a smaller size.UV-Vis absorption of the composite materials indicate that Ag nanoclusters might coexist together with AgCl particles.
