In the context of the CAPTUS project, a new scientific paper about “Advances in the development of innovative Bi-Sn-Sb-based Gas Diffusion Electrodes for continuous CO2 electroreduction to formate” written by the partner Universidad de Cantabria (UNICAN) has been published in the Journal of CO2 utilization.
The study explores Bi-Sn-Sb nanoparticles as electrocatalysts for the electrochemical reduction of CO₂ to formate, showing that small additions of Sb and Sn to Bi enhance catalyst stability without compromising activity or selectivity. In flow cell tests using gas diffusion electrodes, the Bi80Sn10Sb10 composition achieved formate concentrations of ~15 g·L⁻¹ at current densities up to 200 mA·cm⁻², with strong stability over 5 hours. These results highlight the material’s potential for future industrial-scale CO₂ conversion.
