Abstract	Authors review the state-of-the-art understanding of non-precious transition metal oxides that catalyze the oxygen reduction and evolution reactions. Understanding and mastering the kinetics of oxygen electrocatalysis is critical to making use of photosynthesis, advancing solar fuels, fuel cells, electrolyzers, and metal–air batteries. Authors present key insights, assumptions and limitations of well-known activity descriptors and reaction mechanisms in the past four decades. The turnover frequency of crystalline oxides as promising catalysts is also put into perspective with amorphous oxides and photosystem II. They focus on electronic structure parameters that can potentially govern the adsorbate binding strength, thereby providing simple rationales and design principles to predict new catalyst chemistries with enhanced activity.
