The hydrogen rising economy is demanding active and durable electrocatalysts based on low-cost, earth abundant materials for water electrolysis and other electrochemical applications. Green metallurgy offers the possibility to synthese porous materials for a large number of applications.In this work, Ti and Ni electrodes are prepared from powders under a wide range of conditions and are used as working elecrodes in the oxygen evolution reaction and as counterelectrode in the CO2 reduction reaction. 1 The main purpose of this research project is to develop multiporpose stable electrodes with a high concentration of active sites at the surface that can reduce the reaction overpotential.
