Abstract
In this study, a core-shell structured Fe3O4@SiO2-Ag nanocomposite structure was synthesized by in situ wet chemistry method with the help of polyvinylpyrrolidone used as stabilizer and auxiliary. SEM-EDS, XRD, and FTIR analyses were performed for the characterization of nanocomposites. Doping Ag nanoparticles on the silica surface prevent agglomeration and small-sized and highly dispersed Ag nanoparticles are obtained. Fe3O4@SiO2-Ag nanocomposite shows superior photocatalytic activity on Brillant Green dyestuff. The Fe3O4@SiO2-Ag nanocomposite showed superior performance in the photocatalytic degradation of Brillant Green, and even after operating 5 times, there was no significant decrease in the activity of the catalyst and it could be easily recycled by creating an external magnetic field.
