The electrochemical reduction of CO₂ with electricity from renewable sources is a promising way to reduce greenhouse gas emissions while producing useful chemical energy carriers. Copper electrode materials are of particular interest as they have the unique ability to reduce CO₂ to hydrocarbons such as methane, ethane and ethanol. Main topic of my research activities is the model-based and dynamic analyses of the electrochemical CO₂ reduction reaction (CO₂RR) on copper-based electrodes to identify the main limitations and optimise the process in terms of selectivity and efficiency.
