photo-degradation of acid violet, acid blue and methyl orange: photo-catalyst and magnetic cofe2o4–zns nanocomposite preparation of ni , co, cu or ag-doped zns nanoparticles

In this study cofe2o4 nanostructures were synthesized via a facile precipitation method without using any surfactant and capping agent in solvent of water. then zinc sulphides with various doping metals (ni, co , cu and ag) were prepared. finally metal doped cofe2o4-zns nanocomposites were made by a fast chemical procedure. the prepared products were subjected to various analyses of structural (xrd), optical (uv–visible) , the formation of bonds using the (ftir) spectrometry and surface layer morphology via sem. vibrating sample magnetometer shows the ferromagnetic property of the ferrite nanostructures. the photocatalytic behaviour of cofe2o4-zns-metal doped nanocomposites was evaluated using the degradation of three azo dyes (acid violet, acid blue, methyl orange) under ultraviolet light irradiation. the results introduce a nanocomposite with applicable magnetic and photocatalytic performance.
