ELectrochemical Synthesis of Nanometal Oxides based on Iron and Cobalt Nanoparticles

Nanothechnology is one of the most important issues in today societies that is developing fast in all industrial and scientific fields. Perhaps one of the simple nanostructures that has been used widely in industry nowadays is nano metal oxides. One of the best methods for synthesizing nano oxides such as Iron, Cobalt, Copper, etc. is electrochemical deposition that cathodic electrodeposition is one of the subgroups of this method. In this method hydroxide was deposited via cathodic electrodeposition from low temperature 0.005 M FeN𝑂3 bath. The cathodic current density was 2 mA 𝑐𝑚−2. Producing alkali is done near the surface of electrode under the effect of reaction of oxygen pre-reactor such as Nitrat ions. Electrochemical cell include cathode whose material is stainless steel. The XRD pattern confirmed that the prepared sample has a crystal phase FeO(OH). One of the disadvantages of this method that is special to Ironoxide is the low adhesion of the particle to the electrod surface. This problem has been solved approximately by decreasing the movement of solvent and sample molecules via decreasing bath temperature. 13th Annual Electrochemistry Seminar of Iran Materials and Energy Research Center (MERC), 22- 23 Nov, 2017
