Banerji L (2024) Studying the cation dependence of CO2 reduction intermediates at Cu by in-situ VSFG spectroscopy in Chemical Science

 
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 By stabilising/destabilising the different spin states of intermediates we are providing a new way to design electrocatalytic materials with wide impacts on green hydrogen, carbon dioxide utilisation, energy storage materials
