The reverse water–gas shift reaction is crucial for CO₂ conversion using renewable hydrogen, but simultaneously achieving high activity, selectivity, and stability in catalysts remains a challenge. Here, the authors introduce a near-surface “quasi-hyperbaric” ammonia strategy that integrates atmospheric-pressure processing with in situ ammonia decomposition to synthesize a high-energy Mo₂N-based catalyst capable of overcoming these trade-offs.
