Effects of Capping Agent and Surfactant on the Morphology and Size of CoFe2O4 Nanostructures and Photocatalyst Properties

In this work firstly cofe2o4 nanoparticles were synthesized via a hydrothermal method. the temperature, surfactant and capping agent effects on the size of cofe2o4 nanoparticles were investigated. 2-hydroxyacetophenone used as a good capping agent to produce cubic-like nanostructure. when sdbs used as surfactant, particles had spherical morphology. nanoparticle was studied by scanning electron microscopy, x-ray diffraction, and fourier transform infrared. we found that the cofe2o4 nanoparticles were prepared exhibit a ferromagnetic behavior with a saturation magnetization of 20emu/g and a coercivity of 250 oe. the photocatalytic behavior of cofe2o4 was studied by the degradation of a methylene blue aqueous solution under ultraviolet light irradiation.
