The cathodic reduction of nitrogen (N2) gas in molten chloride was investigated using a porous nickel (Ni) electrode. A LiCl-KCl-CsCl melt containing cathodically formed nitride ion (N3−) was sampled from an electrolytic bath and analyzed quantitatively by ion chromatography. The current efficiency of the cathodic reaction calculated from the ratio of quantity of the produced N3− was approximately 78% on average. The main reason why the measured efficiency did not reach 100% is considered as the amount of N3− increased more in the pores of the gas electrode than in the bulk of the electrolytic bath.
