Transition metal suffer from severe in acid, causing degradation (e.g., in ORR) and false positives (e.g., in N2RR). In Joule today, we develop to stabilize nitrides in acid (e.g., for ). ⚡️ doi.org/10.1016/j.joule.2022.1

Transition metal nitrides have suffered from severe nitride dissolution and subsequent ammonia generation in acidic electrolytes, limiting the use of earth-abundant nitride catalysts in proton exchange membrane fuel cells and electrolyzers. Combining theory and experiment, we have established design principles governing the extent and kinetics of nitride decomposition and ammonia production in acid. Guided by these insights, new nitride catalysts can be rationally designed with optimized stability in acid to electrify and decarbonize the production and utilization of chemicals and fuels.

It has been a fun collaboration between the Electrochemical Energy Lab (at MIT MechE & DMSE) and the Roman group (at MIT ChemE), funded by Toyota Research Institute. 🧑‍🔬
