An important hurdle in water electrolysis originates from the fact that the reactants of the anode reaction, the oxygen evolution reaction, are singlet molecules, whereas the oxygen molecule has a triplet ground state with parallel spin alignment. In line with this idea, enhanced OER activity was achieved by inducing ferro- and ferrimagnetic long-range magnetic order in catalysts, but the enhancement mechanism remains largely elusive. Using X-ray Magnetic Circular Dichroism (XMCD) this study will provide insights into the magnetic behavior of thin film oxide catalysts under operando OER conditions which will directly connect the spin-spin interactions in the catalyst to the (changes in) OER activity. This understanding will enable us to shine light on the magnetic dependent OER mechanism.
