Zusammenfassung:Cobalt ferrite, titanium dioxide nanoparticles and finally magnetic CoFe 2 O 4 –TiO 2 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, CoFe 2 O 4 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 CoFe 2 O 4 –TiO 2 nanocomposite was evaluated using the degradation of various organic dyes aqueous solution under UV light irradiation. The results confirm that CoFe 2 O 4 –TiO 2 nanocomposites have suitable performance in photo-catalytic applications. The results show that the CoFe 2 O 4 –TiO 2 can enhance the flame retardant property of the PVA matrix.
