For the electrochemical conversion of the greenhouse gas CO2 into products of higher value catalysts for two half-cell reactions need to be developed, i.e. catalysts for the reductive conversion of CO<sub>2</sub> (CO<sub>2</sub>RR) as well as catalysts for the oxidative splitting of water (OER: Oxygen Evolution Reaction). In research, the catalysts are often investigated independently of each other as they can later easily be combined in a technical electrolysis cell. CO<sub>2</sub>RR catalysts consist of abundant materials such as copper and silver and thus mainly the product selectivity of the respective catalyst is in focus of the investigation. In contrast to that, OER catalysts (in acidic conditions) mainly consist of precious metals, e.g. Ir, and therefore the minimization of the catalytic current per gram Ir is of fundamental importance.</p>}, number={9}, journal={CHIMIA}, author={Dutta, Abhijit and Bizzotto, Francesco and Quinson, Jonathan and Zana, Alessandro and Morstein, Carina Elisabeth and Rahaman, Motiar A and López, Alena Cedeño and Arenz, Matthias and Broekmann, Peter}, year={2019}, month={Sep.}, pages={707} }
