Upgrading the detection of electrocatalyst degradation during the oxygen evolution reaction

Electrocatalysts for the oxygen evolution reaction (OER) are an important component transition from fossil to sustainable energy. Commercialization of cost-effective earth-abundant electrocatalysts is in large parts hindered by their degradation. In this short review, I identify common processes leading a decrease electrocatalyst activity, followed introduction staple methods determine degradation electrochemically and additional physical characterization, which has potential remove ambiguities purely electrochemical studies. conclude summary key challenges accurate determination highlight interesting directions advance understanding on materials-centered model
