Tuning Active Hydrogen on Reconstructed RuO₂/Co(OH)₂ Catalysts for Selective Ammonia Synthesis.

ABSTRACT: The electrochemical nitrate reduction reaction (eNO₃RR) is widely recognized as a promising strategy for sustainable ammonia production and supporting the nitrogen cycle. However, its advancement is impeded by complex behavior of reaction intermediates and the inevitable reconstruction of precatalysts. To address these challenges, the generation and utilization of active hydrogen (*H) are strategically managed by tailoring the RuO₂/Co₃O₄ precatalyst and optimizing the electrolyte composition (OH^- and NO₃ ^- concentration), thereby selectively enhancing ammonia formation. Consequently, the in situ reconstructed RuO₂/Co(OH)₂ catalyst achieves an impressive ammonia yield of 35.9 ± 0.9 mg h^-1
