In the last decades, the amount of CO₂ in the earth’s atmosphere has increased enormously. Due to the goals set by Europe, CO₂ mitigation is of major importance for industry as well as society. In this project we will focus on the electrochemical reduction of CO₂. However, this reaction pathway can only become cost-effective by reducing the large overpotential for the electrochemical CO₂ reduction and thus, directs the problem towards the world of electrocatalysis. More specific, the catalytic properties of bimetallic Cu/Ag core-shell nanoparticles on the reduction of CO₂ into valuable C1-C3 hydrocarbons will be investigated. Electrochemical measurements will provide an insight in the reaction pathway and this information will be used to adjust the electrodeposition of the NP’s and optimizing the core-shell NP morphology of the catalysts. In addition, this project will combine the design and synthesis of these electrocatalysts with the engineering of an electrochemical membrane flow microreactor (including the electrode structure and cell construction). In our opinion, it is this combination that provides the next step in the improvement of CO₂ reduction to fuels and chemical building blocks.
