Nature Communications, Published online: 20 June 2026; doi:10.1038/s41467-026-74660-2 The authors report a practical and divergent electrochemical method for converting simple secondary amines into thiocarbamoyl fluorides and N-trifluoromethyl amines, proceeding under mild, open-air conditions without solvent drying, degassing, inert atmosphere, or stoichiometric silver reagents.

The persistence of fluoroquinolone antibiotics like ofloxacin (OFL) in aquatic systems leads to emergence of antimicrobial resistance (AMR) and need better technology to monitor its effects on the environment/health. The implementation of real-time and decentralized monitoring systems remains constrained due to their dependency on slow and resource-intensive technique. To overcome these challenge…

Recently, metal oxides have attracted great attention as materials for electrochemical biosensors due to their low cost, functional biocompatibility, excellent chemical stability in biofluids and easy anchoring of biorecognition molecules. Drawbacks limiting their practical use in devices are the low conductivity and electron transfer kinetics. Nanostructural forms of metal oxides could overcome …

Nature Communications, Published online: 16 June 2026; doi:10.1038/s41467-026-74475-1 Electrocatalytic NO reduction to NH3 is hindered by insufficient NO activation. Here, the authors report Cu1−Ti pairs that integrate the N affinity of Ti and O affinity of Cu to efficiently activate NO via bidirectional electron donation, thus achieving a high NH3 yield and Faradaic efficiency.

Nature Communications, Published online: 15 June 2026; doi:10.1038/s41467-026-74349-6 An oxidant-free electrocatalytic system with an I-BiOI@CC anode is developed for phenolic polymerization via iodinemediated proton-coupled charge transfer, converting pollutants into recoverable solids with 97.1% selectivity and low toxicity.

Nature Communications, Published online: 15 June 2026; doi:10.1038/s41467-026-74410-4 Efficient carbon dioxide reduction to multi-carbon products in acidic media is hindered by competing hydrogen evolution. Here, the authors report a hybrid catalyst that regulates proton transfer to drive highly selective multi-carbon formation at high current densities.

Nature Communications, Published online: 13 June 2026; doi:10.1038/s41467-026-74340-1 Lithium metal batteries face challenges with dendritic growth. Here, authors employ in situ TEM to reveal how specific electrolyte anions dictate lithium nucleation and interphase architecture, establishing design principles for suppressing dendrites and enabling stable lithium deposition.

Nature Catalysis, Published online: 11 June 2026; doi:10.1038/s41929-026-01554-3 Electrocatalysts for ammonia oxidation tend to be poisoned by nitrogen-based intermediates. Here the authors use an electrode-alternating strategy that uses pulsed potential reversal to continuously regenerate the deactivated surface, enabling Pt-based ammonia electrolysis for over 1,000 h.

Herein, a straightforward, and mild synthetic co-precipitation method is used to prepare Cr-ZnO/RGO nanocomposite to be used in supercapacitor applications. First, the chromium (Cr) doping concentration in zinc oxide (ZnO) nanoparticles was systematically varied (2, 4, 6, 8, and 10%) to evaluate its influence on the electrochemical performance. The composite was constructed by combining reduced g…
