    Photocatalytic dye degradation has been widely studied in recent years because of increasing global pollution resulting from toxic colouring dyes. In this work we report on the synthesis of a novel recyclable core-shell nanocomposite consisting of CoFeČ2O4 (CFO) as magnetic core and polyaniline (PANI) as shell with silver nanoparticles embedded in it for photocatalytic dye degradation application. Co-precipitation method has been employed for the synthesis of CFO followed by oxidative polymerization of aniline monomer. Freshly prepared Ag nanoparticles have been added during polymerization. Core-shell nanoparticles of 10-15 nm size were obtained which was confirmed by XRD and TEM analysis. EDAX confirms the respective elemental compositions of CFO, PANI, and Ag. The photocatalytic efficiency of the obtained nanocomposite has been tested on methylene blue dye under sun light. The composite shows an efficiency of ~ 90% which shows promise to be a good catalyst for photocatalytic dye degradation.
