  • ELECTROCHEMICAL RECYCLING OF HOMOGENEOUS CATALYSTS
    Publication number: 20240352610
    Abstract: Herein disclosed is a new electrochemical approach to catalyst capture and recycling that overcomes conventional industrial recovery methods using functionalized redox-polymer electrodes. This technology provides a redox electro-separation system comprising polyvinylferrocene that was able to capture platinum group metal based catalysts directly from products and transfer to fresh reactants achieving 99.5% recovery without disturbing catalyst activity. Several reactions were tested along with various solvent-electrolyte matrices, showing >99% recovery efficiencies for platinum species as low as 1.6 ppm.
