Ammonia (NH3) is essential for fertilizers and emerging carbon-free energy technologies, yet its conventional production via the Haber-Bosch process is energy-intensive and CO2-emitting. Researchers from Tohoku University and collaborating institutions have now established a structural blueprint for deploying 3D COFs in electrocatalysis, opening new routes toward sustainable nitrate management and decentralized ammonia synthesis. The work was published in the Journal of Materials Chemistry A on February 2, 2026.
