Ion swap dramatically improves performance of CO₂-defeating catalyst

Researchers at Oak Ridge National Laboratory have improved a catalyst for converting CO₂ to methanol by swapping ions in its support structure. By replacing oxygen anions with hydrogen anions in barium titanate, they tripled the methanol yield. This ion swap enhances the interaction between copper nanoparticles and the support, boosting the catalyst’s efficiency and stability. This method offers a new way to design better catalysts for carbon capture and conversion technologies, contributing to efforts to achieve net-zero carbon emissions by 2050.
