Abstract: In the recent decade Nanoparticles (NPs) of transition elements have been researched upon widely for their numerous uses in various fields, varying from biological, catalytic to anti-oxidant applications [1]. Iron (III)Oxide nanoparticles are widely synthesized and are known for their numerous applications. Iron (III)Oxide (Fe2O3) in the present work were synthesized by Co-precipitation method. Cobalt Ferrite nanoparticles (CoFe2O4) have been synthesized and the method which was devised was again Co-precipitation method [8, 9], followed by calcination at 800 ͦC for a period of 3 hrs. [4]. The concentration of Cobalt has been taken as 10% and that of Iron Oxide is of 90%in the synthesis of Cobalt ferrite nanoparticles. Further, doping has been carried out with Sodium in Cobalt Ferrite nanoparticles. In the process of doping the concentration of dopant i.e. Sodium has been kept constant while the concentration of Cobalt and Iron Oxide has been varied. Three doped samples have been prepared, in which concentration of Cobalt is 1%, concentration of Sodium is 1%, and as for Iron Oxide it is 98% Na(0.001)Co(0.001)Fe2O3(0.098) [4]. Sodium Hydroxide (NaOH) has been used as the base to maintain a pH of 11. Polyethylene Glycol has been used as the surfactant. XRD, SEM -EDX and TEM results confirms the formation of Iron Oxide, Cobalt Ferrite nanoparticles and Sodium doped cobalt ferrite nanoparticles. Photocatalytic activity of Iron (III)Oxide, Cobalt Ferrites and sodium doped Cobalt ferrites has been studied by studying the process of degradation of a dye by UV analysis of the samples. The rate of the photocatalytic activity at various quantities of nanoparticles has been discussed in the present work.
