characterisation. Collectively, these studies reveal that manipulating spin polarisation at active sites can accelerate multi-electron transfer pathways, alter intermediate binding, and enhance overall catalytic performance beyond classical design limits. Finally, we highlight remaining mechanistic ambiguities, emerging diagnostic tools, and future opportunities for integrating spin physics into scalable electrocatalyst development.
