Ensuring a sustainable future and reducing carbon emissions heavily relies on renewable energy sources. These sources allow us to harness electrons to drive chemical reactions and store energy in the form of chemical bonds. However, the performance of current electrocatalytic processes needs significant improvement. 

Magnetic field effects on electrocatalysis have recently gained attention due to the substantial enhancement of the oxygen evolution reaction on ferromagnetic catalysts. In this context, it is crucial to carefully characterize how magnetic fields affect mass transfer of charged reactants and products at the interfacial level, a phenomenon that occurs even on non-magnetic electrodes and is often overlooked.

In this talk, I will highlight the use of unconventional strategies to achieve spin control of reaction pathways on the surface of a catalyst.  By decoupling the effects involved in global (interfacial) vs local magnetic enhancement using in situ techniques,  I will provide a versatile strategy that can be easily implemented to boost electrocatalytic reactions across diverse materials.
