  • One major problem with renewable energy sources such as solar and wind power is their intermittent supply. Here the authors present an Earth-abundant manganese oxide electrocatalyst that is resilient to voltage fluctuations and maintains oxygen evolution reaction activities for 2,000 h.

  • Precious-metal-free catalysts for water oxidation commonly suffer from low stability in acidic electrolytes. Now, by controlling the intergrowth of the γ-MnO2 structure, it has been possible to achieve 2 A cm−2 at 2 V and a stability of over 1,000 hours at 200 mA cm−2 in a polymer electrolyte membrane electrolyser.
