The spinel semiconductor oxide found in the formula AB2O4 for normal spinel structure, where A is a divalent cation that usually occupy the tetrahedral sites and B is a trivalent cations that normally occupy the octahedral sites in the spinel cubic structure. Another type of spinel structure is an inverse has the form B(AB)O4, where B is a trivalent metal cation, half of this cation occupy the tetrahedral sites and another occupy the octahedral sites, A is divalent metal cation occupy an octahedral site in spinel [1,2]. The most interesting spinel structure materials in the magnetic and electrical field usually include iron and cobalt at various oxidation states [3-5]. The transition metal oxides which defined are compounds consist of oxygen atoms coalescence to transition metals [6,7] and used as a photocatalysis in wastewater treatment [8], these catalyst were capable of absorbing light and creating electronhole pairs that allow electronic transition in the reaction because of the formation of positive holes, which resulted from the transfer electron from the valence band to the conduction band of semiconductor by absorbing energy from UV light, visible light or both producing an electron/hole pair (e-CB/h + VB) which is able to reduce and/or oxidize compound and degrade of pollutants in aqueous solution by using solid heterogeneous catalyst such as mixed metal oxides, which have wide applications as catalyst
