  • Electrocatalysts for CO2 reduction are typically prepared and optimized ex situ before the reaction begins, but during reactions they may undergo changes that lower their performance. Here the authors show that active Cu catalysts can be formed on a recoverable basis and removed in situ during the CO2 reduction reaction, improving the stability of the system.

  • Cobalt–iron–lead oxide electrocatalysts show promise for the low-pH oxygen evolution reaction—an essential reaction in proton-exchange water electrolysis—but can suffer from corrosion. This study uncovers that the mechanism of cobalt site corrosion is decoupled from the oxygen evolution reaction, paving the way for more stable catalyst designs.

  • The development of an effective, cheap and robust water oxidation catalyst is crucial to the development of solar water-splitting technology. A manganese catalyst inspired by the water oxidizing centre of photosystem II is now shown to dissociate and reform into nanoparticles resembling the known natural oxidant mineral birnessite.

  • The traditional Haber–Bosch process as well as recent alternative approaches based on photo- or electrocatalysis all rely on solid catalysts to convert nitrogen into ammonia. Here the authors disclose an effective method for the synthesis of this crucial commodity based on a Cu–Ga liquid metal catalyst instead.

  • Producing H2 from water using electricity and earth-abundant elements is necessary for worldwide renewable fuel production, yet most electrocatalysts have sluggish activities or poor stabilities. Here, authors show vanadium oxide modified copper-doped nickel to enable active and durable H2 evolution.

  • Electrochemical water splitting in acidic conditions is limited by the lack of inexpensive and stable anode catalysts. Now, Simonov and colleagues report a non-noble metal-based oxygen evolution catalyst formed in situ that exhibits high stability for acidic water oxidation due to a self-healing mechanism.

  • Ni–Fe based compound are known as active electrocatalysts for oxygen evolution reaction, but not a good choice for the other half-reaction of water-splitting. Here the authors report a unique interface between Ni and γ-Fe2O3 that efficiently catalyzes the cathodic hydrogen evolution reaction.
