Implication

Analysis shows high ammonia selectivity in photocatalytic nitrate reduction with Ag-Cu dual-atom catalyst, indicating effective spatial decoupling.

Key Points

  • The AgCu-CN catalyst achieves an impressive 98% ammonia selectivity during nitrate reduction.
  • Production rate of 630.5 µmol h −1 g −1 establishes the catalyst's state-of-the-art performance.
  • In situ studies confirm that the dual sites in catalysts are crucial for optimizing selectivity.
  • This design principle provides insights into addressing selectivity challenges in complex reactions.
