Introduction The dependence between the energies of different intermediates during a catalytic cycle, known as linear-scaling relationships (LSR), limits the maximum efficiency achievable for a process.1 To enhance the activity of catalysts, these LSRs must be circumvented, for instance by applying external stimuli.

Abstract Electrocatalytic processes involving the oxygen evolution reaction (OER) present a kinetic bottleneck due to the existence of linear-scaling relationships, which bind the energies of the different intermediates in the mechanism limiting optimization. Here, we offer a way to break these scaling relationships and enhance the electrocatalytic activity of a Co–Fe Prussian blue modified electrode in OER by applying external stimuli.
