The main focus is producing green hydrogen using renewable electricity and water electrolysis to reduce the carbon footprint. Thus, highly active and stable mixed oxides CoNiFeOx electrocatalysts for alkaline OER have been developed and investigated to improve the overall efficiency of water electrolysis. The side topic is converting CO2 into valuable carbon products through an electrochemical reduction reaction.
