Unlocking a Water Coordination Environment in Co-Based Metal-Organic Frameworks for Advanced Nitrate-to-Ammonia Electroreduction.

ABSTRACT: Electrochemical nitrate reduction to ammonia (e-NO₃RR) offers a promising and sustainable alternative to the traditional Haber-Bosch process, enabling decentralized ammonia production under ambient conditions. However, the efficiency of e-NO₃RR is limited by the sluggish reaction kinetics due to the high activation energy barriers, poor mass transport, and the weaker adsorption affinity of the catalyst surface. In this study, we report the design and synthesis of a stable three-dimensional cobalt-based metal-organic framework (HUST-38), constructed from benzene-1,4-dicarboxylate ligand and DABCO, featuring water coordination within its framework. Impressively, the as-prepared HUST-38 delivers a high NH₃ Faradaic efficiency of 95.7% and a high
