Carbon-based materials and chemicals are essential in daily life, ranging from cosmetics to plastics and fuels. Alternative processes, such as CO₂ electroreduction powered by renewable energy (wind, solar, tidal), can enable more sustainable production of carbon-based chemicals, but typically suffer from poor stability.
In this project, we investigate how the electrocatalyst and cell-components used in CO₂ electroreduction degrade under high current densities and prolonged operation. Using in-situ and operando X-ray techniques, we aim to understand the compositional and structural changes that affect catalyst activity and selectivity at more industrially relevant conditions (e.g. high current density). These insights will contribute to the nationwide consortium HyCARB (GroenvermogenNL), which aims to bring sustainable routes for carbon-based materials and chemicals closer to scaling-up in chemical industries.
