Two‐Step Tandem Catalysis for High‐Efficiency Ammonia Synthesis Via Nitrate Reduction on Anion‐Intercalated CoNi LDH and Cu/Cu2O

open access: yesAdvanced Science, EarlyView.
By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.
