A new study from the CAPTUS project, titled “GDE Stability in CO2 Electroreduction to Formate: The Role of Ionomer Type and Loading”, has been published by the partner Universidad de Cantabria (UNICAN) in the ACS Catalysis journal.
The article explores how tuning the catalyst layer composition can improve the long-term stability of gas diffusion electrodes for electrochemical CO₂ reduction to formate. By using Sustainion instead of Nafion and adding PTFE to adjust hydrophobicity, the study achieves high formate selectivity and 24-hour stable operation – key steps toward scalable, efficient CO₂-to-formate conversion.
The article is already available in the scientific publication section on our website as well as in the dedicated CAPTUS community on Zenodo.
