  • The design of efficient and stable oxygen evolution catalysts has implications for water splitting and metal-air battery technology. Here, the authors fabricate double perovskite nanofibers and demonstrate the favourable effects of co-doping and nanostructuring on oxygen evolution performance.

  • Large potentials required for C(sp3)-H bond activation and low water solubility make electrochemical functionalization of alkanes challenging. Here, the authors report that Pt/IrOx enables selective generation of Cl free radicals for chlorination of cyclohexane at industrially relevant rates.

  • One limiting factor to the high-performing reversible protonic ceramic electrochemical cells is the poor stability and electrocatalytic activity of air electrodes. Here the authors report a water-promoted surface restructuring process to enhance the performance of Ba0.9Co0.7Fe0.2Nb0.1O3-δ air electrode.

  • Proton-coupled electron transfer (PCET) has been observed in chemical, energy, and biological transformation processes. Here we demonstrate that the rate of PCET and oxygen evolution reaction can be dramatically enhanced by tuning crystal orientation and the correlated proton diffusion.

  • Solid oxide fuel cells are most commercially viable when run at low temperatures, but this makes it challenging to achieve high performance with hydrocarbon fuels. Here the authors report a fuel cell running at 500 °C on nearly dry methane that incorporates a Ni–Ru–CeO2-based reforming catalyst, achieving high power densities and coking resistance.

  • Proton-exchange membrane water electrolysers often rely on scarce iridium or ruthenium catalysts at the anode, as many low-cost, earth-abundant catalysts cannot withstand the harsh operational conditions. This Review discusses the state of the art in earth-abundant water oxidation catalysts and examines their degradation mechanisms at multiple levels.

  • Three kinds of Ni3S2 nanostructures, namely Ni3S2 nanorods, Ni3S2 nanosheet@nanorods and Ni3S2 multi-connected nanorods were prepared using a one-step hydrothermal process via controlling the temperature. Owing to the good mechanical adhesion and electrical connection with the substrate, high contact area with the electrolyte and alleviated structural pulverization during the ion insertion/desertion process, Ni3S2 nanosheet-onto-Ni3S2 nanorods exhibited excellent rate capability and cycling stability. Asymmetric supercapacitor consisting of Ni3S2 nanosheet @nanorods electrode and activated carbon (AC) electrode displayed a volumetric energy density of 1.96 mWh cm−3, which can be used to bridge the performance gap between thin-film Li batteries and commercial AC//AC supercapacitors.
