Abstract

In situ DRIFTS measurements of an Fe/BZY-Ru cathode catalyst in an electrolysis cell using a CsH2PO4/SiP2O7 electrolyte were carried out in a mixed N2–H2 gas flow under polarization. The formation of N2Hx species was confirmed under polarization, and an associative mechanism in the electrochemical NRR process was verified.
