Preparation of Cobalt Ferrite Nanoparticles Using Fulvic Acid as A Capping Agent and Its Effect on Catalytic Activity

LIJinxing, BadawyAbdelrahman A., DUGuanben, ZHOUXiaojian, EssawyHisham A.


Cobalt ferrite was prepared by co-precipitation from cobalt and iron soluble precursors in presence of fulvic acid at different pH values, namely, 6 and 8 and compared with the same preparation in absence of fulvic acid. The presence of fulvic acid is expected to bind metal ions through bridging before co-precipitation and mineralization. The extent of binding is determined according to the pH of the process. This influences the mineralization of the resulting cobalt ferrite and the crystallization/ordering of its lattice. In addition, the extent of residual ferric oxide is also a function of the efficiency of binding process. This route of modification for the co-precipitation process was found to be accompanied by enhanced surface area and total pore volume for most of the prepared samples. The involvement of these oxides as catalysts in the photo-catalytic degradation of phenol from wastewater was found to contribute very efficiently and the removal reached about 88% in some cases, which can be attributed to olation and oxolation process of the formed nanoparticles.
