Electrochemical deposition of porous Cu and Cu-Zn and investigation of hydrogen evolution reaction about them

Nano porous metals with nano porosity because of a very high specific surface area of them, low density and good catalytic activity have unique chemical, physical and mechanical properties. Due to these advantages they can be used as an electrocatalyst in several reactions. In this work we used them for investigation of hydrogen evolution reaction. During that, at first we deposited Cu and Cu-Zn by electrochemical method and investigated by scanning electron microscopy. After that we used mentioned electrodes as cathode in hydrogen evolution reaction and compared with each other by linear sweep voltammetry and chronoamperometry. Results showed that electrochemical performance of porous Cu-Zn electrode is better than porous Cu. Also porous Cu showed porosity has an important effect on electrochemical properties of metals.
