    Reversible electrochemical cells can operate in both fuel cell and electrolysis modes to interconvert between chemical and electrical energy. Here, Duan et al. design a reversible protonic ceramic electrochemical cell that operates stably at 500–600 °C, with high Faradaic and round-trip efficiencies, by minimizing electronic leakage.

    Metal–organic frameworks (MOFs) are increasingly being explored as electrocatalysts for the oxygen evolution and reduction reactions, which are important processes in electrolysers and fuel cells. Here, the authors increase the activity of MOFs for these reactions by introducing strain into the lattice using UV light illumination.

    Water may serve as a renewable hydrogen fuel source to replace fossil fuels, although such electrolysis requires highly active catalysts. Here, authors explore Ruddlesden−Popper oxides as hydrogen evolution electrocatalysts that feature an unusual synergistic effect to promote high activity.

    Integrating electrocatalytic H2 production with biological H2-fed systems for CO2 upgrading requires H2 generation to occur in biocompatible media—typically with neutral pH. Here, the authors design multi-site H2 evolution catalysts that minimize the water dissociation barrier and promote hydride coupling in neutral media.

    Scalable interconversion between chemical and electrical energy requires compact, selective and highly efficient reversible electrochemical cells. Now, protonic electrochemical cells with tailored catalysts and ceramic architecture are shown to operate reversibly with high performance and to be integrable with catalytic CO2 conversion.

    Ammonia holds promise as a clean energy carrier, but its synthesis requires high pressures and large production scales that are ill-matched to renewable, decentralized energy production. Now, researchers use metal imides to mediate ammonia production in a chemical looping process that operates under mild conditions.

    Semi-artificial photosynthesis offers advantages over purely natural or synthetic routes to producing chemicals from solar energy, but devices based on it have remained elusive. Now, researchers couple a dye-sensitized photoanode with natural components to generate H2 photoelectrochemically from water without additional bias.

    Development of an earth-abundant and inexpensive copper-based catalyst is desirable for CO2 hydrogenation. Now, the combined application of a stable copper hydride and a Lewis pair is shown to effect activation of CO2 as well as heterolysis of H2, achieving significant turnover numbers.

    Photocatalytic water splitting is a route to clean H2, but approaches based on hybrid semiconductor–metal nanoparticles often rely on sacrificial reagents to complete the oxidation half of the overall reaction. New research uses CdS nanocrystals modified with metallic and molecular co-catalysts to simultaneously produce H2 and O2 from water using visible light.
