| Description | New electrode structures which generate out of plane magnetic fields and possible spin polarisation of the current have been prepared and tested for three model reactions. Studies on carbon dioxide reduction indicate that the magnetic field may inhibit activity. Studies on water oxidation show an increase in activity with gold electrodes, traditionally a less active surface. Hydrogen evolution can be supressed in acid but enhanced in alkali due to an interplay of spin and magnetic effects. Overall we believe we have demonstrated that we can decouple spin-state control from magnetic field effects during electrocatalysis. A manuscript is in preparation as is a patent filing. |
| Exploitation Route | Contact industry for potential commercial development -but first further research is needed to confirm the findings and see potential for scaling etc. |

| Sector | Academic/University |
| PI Contribution | Leeds has fabricated thin film multilayers of Pt/Co superlattices and characterised their magnetic properties. |
| Collaborator Contribution | Liverpool (partners in this grant application) did potentiostatic/catalysis measurements. The ALBA synchrotron is characterising the Xray absorption edge of these samples to analyse their surface chemistry post-measurements. |
| Impact | This is a multidisciplinary collaboration between solid state physicists with expertise on nanomagnetism, chemists working on catalysis and synchrotron scientists. |
