A structurally self-sustaining amorphous Cu-Co catalyst for robust electrochemical NO-to-NH3 conversion at industrial current densities.

A novel amorphous Cu-Co catalyst is developed and achieves a high faradaic efficiency of over 90% for electrochemical NO-to-NH3 conversion. Importantly, the structure of the catalyst remains unchanged under electroreduction conditions due to an intrinsically disordered, reconstruction-resistant framework that suppresses phase transformation and surface restructuring, delivering long-term stability over 20 h at 200 mA cm-2.
