Electrocatalytic Study of Fe, Ni, Zr and Cu Complexes and Their Alumina Supported Catalysts

The behavior of complexes of iron, nickel, zirconium and copper as an electrode in alkaline, acidic and neutral solution has been investigated primarily by cyclic voltammetry. Cyclic voltammetry is a classical measuring method in electro-analytic chemistry which is used for the study of catalysis and charge transfer. For the complexes [Fe–Cu], [Ni–Ni], [Zr–Zr] and [Cu–Cu] as well as for supported catalysts, it was possible to determine various oxidation reactions with the cyclic voltammetry method. For this method, these complexes and catalysts were coated on nickel electrodes and using cyclic voltammetry following reactions were carried out (a) oxidation of CH3OH, (b) oxidation of NaCl and (c) oxidation of NaOH. The cyclic voltammogram presented in this work were shown to have different oxidation states and reduction states depending upon the kind of chemical reaction carried out, nature of complex utilized, the nature of support as well as how the complex is bonded to the support.
