Dynamic multimodal cation-carbon interaction for efficient adiponitrile electrosynthesis.

Dynamic cation-carbon interactions enable efficient adiponitrile electrosynthesis on carbon electrodes, achieving high selectivity at significantly lower overpotentials in large-scale systems.

• Why it matters: Current acrylonitrile reduction methods rely on toxic heavy-metal electrodes and have low energy efficiency, limiting sustainable industrial production of adiponitrile for nylon manufacturing.
• What they did: Researchers employed a strategy using benzyltrihexylammonium cations to create a water-depleted interface via multimodal noncovalent interactions, optimizing the microenvironment on carbon electrodes in aqueous electrolytes, tested from lab scale to 159 cm² electrolyzers.
• The result: This approach matches the selectivity of lead-based systems but with much lower energy input, demonstrating the potential for environmentally friendly, scalable organic electrosynthesis through tailored cation-electrode interactions.
