Photo-catalyst CoFe2O4–TiO2: application in photo-degradation of organic dyes and magnetic nanocomposite preparation

Cobalt ferrite, titanium dioxide nanoparticles and finally magnetic CoFe2O4–TiO2 nanocomposites were synthesized via a simple hydrothermal reaction using. The effect of various precipitating agents such as ammonia, sodium hydroxide, ethylene diamine, hydrazinium hydroxide and different surfactants on the morphology of the products was investigated. For preparation of magnetic nanocomposite, CoFe2O4 was added to poly vinyl alcohol. The magnetic properties of the product were also investigated using a vibrating sample magnetometer. The nanoparticles exhibit various ferromagnetic behaviours by changing in surfactants at room temperature. The photocatalytic behaviour of CoFe2O4–TiO2 nanocomposite was evaluated using the degradation of various organic dyes aqueous solution under UV light irradiation. The results confirm that CoFe2O4–TiO2 nanocomposites have suitable performance in photo-catalytic applications. The results show that the CoFe2O4–TiO2 can enhance the flame retardant property of the PVA matrix.
