Enhanced Control on the Electro Deposition Through Magnetic Field Using Reverse Microemulsion as Template

摘要

Reverse micro emulsion is often used for the synthesis of metal nanoparticles. Such prepared metallic nanoparticles may be used as catalyst for oxidation of methanol occurring in fuel cell. Nickel electrodes were modified by electro chemical deposition of the nickel nanoparticles. In-continuous deposition was occurred on using reverse micro emulsion. This problem was addressed on having the same in the presence of magnetic field. In fact, Lorentz force started playing role in terms of large mass transfer rate when magnetic field perpendicular to the direction of current was applied. Surface analysis of the both types of the modified electrode was done with the help scanning electron microscopy. Electro chemical and catalytic studies of both modified electrodes were done. Results of these studies encouraged the employment of the magnetic field during the electro chemical deposition of the metals.
