Abstract
Lithium-mediated nitrogen reduction (LNRR) shows promise for sustainable NH3 production, but flow electrolyzers incorporating gas-diffusion electrodes (GDEs) have rarely been studied toward this application. This work investigates cathode GDEs using inexpensive carbonaceous reaction layers to achieve stable and active NH3 electrosynthesis for over 8 h under pulsed currents. Particularly, the amorphous C45 demonstrates superior durability over Vulcan, Vulcan-supported Pt, and graphitic SFG6L at −5 mA cm–2. Replacing Nafion with polyvinylidene fluoride as the binder improves the NH3 production rate (3.11 ± 0.41 μmol h–1 cm–2) and Faradaic efficiency (5.0 ± 0.65%), outperforming prior precious-metal-free cathode results.
期刊介绍：
ACS Applied Energy Materials is an interdisciplinary journal publishing original research covering all aspects of materials, engineering, chemistry, physics and biology relevant to energy conversion and storage. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrate knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important energy applications.
