Generation of Ammonia in a Pulsed Hollow Cathode Discharge Operated in an Ar/H<sub>2</sub>/N<sub>2</sub> Gas Mixture Detected by Fourier Transform Infrared
A hollow cathode discharge with a copper nickel cathode (Cu50Ni50) was operated in an Ar/H<sub>2</sub>/N<sub>2</sub> gas mixture. Optical emission spectroscopy revealed the formation of NH radicals, which serve as precursors for NH<sub>3</sub> formation. Ion mass spectrometry showed the formation of NH<sub>3</sub> <sup>+</sup> and NH<sub>4</sub> <sup>+</sup> ions indicating NH<sub>3</sub> formation. Gas samples taken at the exhaust of the vacuum system were analyzed by Fourier transform infrared spectroscopy. Clear evidence for NH<sub>3</sub> formation was obtained from these measurements.
