  • Use of a chain-ether-based solvent instead of tetrahydrofuran for lithium-mediated nitrogen reduction enables long-term continuous ammonia electrosynthesis with high efficiency and improved gas-phase ammonia distribution.

  • The proton shuttle plays a critical role in the proton transfer process during lithium-mediated ammonia synthesis. Here, the authors establish the structure-activity relationship and design principles for effective proton shuttles.

  • The production of ammonia via the Haber–Bosch process is carbon-intensive and centralized, but electrochemical methods such as lithium-mediated processes in organic electrolytes could enable decentralized production using renewable energy. Calcium is now shown to mediate nitrogen reduction for ammonia synthesis.

  • Controlling surface structure at the atomic scale is paramount to developing effective catalysts. The surface structure of MoS2 is now engineered to preferentially expose edge sites by successfully synthesizing contiguous large-area thin films of a highly ordered double-gyroid MoS2 bicontinuous network with nanoscale pores.

  • Catalytic ammonia synthesis continues to attract significant interest. Here, the authors develop a model to explain a large body of recent experimental data on new promoters. They find new promotion mechanism mediated by coupling between adsorption and spin polarization on the surface atoms of magnetic catalysts.

  • Low-cost, high-performance oxygen evolution catalysts would facilitate implementation of water electrolysers for hydrogen production. Here the authors report a low-iridium mass-selected iridium–tantalum oxide catalyst with high intrinsic activity in acid and carefully evaluate oxygen production to account for parasitic reactions.

  • Non-noble-metal-based MoS2 nanostructures are hydrogen evolution catalysts whose active sites are known to be located at the edges. Supported thiomolybdate [Mo3S13]2− nanoclusters have now been prepared that exhibit a structural motif similar to that of MoS2 edges. The nanoclusters, synthesized by a scalable route, demonstrate a high turnover frequency.

  • A wealth of candidates are being investigated to improve the catalysts found in acidic and alkaline electrolysers. However, attention should be focused on developing stable water oxidation catalysts with improved intrinsic activity — not only increased geometric activity — alongside best practice for data collection.
