A hollow cathode discharge with a copper nickel cathode (Cu50Ni50) was operated in an Ar/H2/N2 gas mixture. Optical emission spectroscopy revealed the formation of NH radicals, which serve as precursors for NH3 formation. Ion mass spectrometry showed the formation of NH3+ and NH4+ ions indicating NH3 formation. Gas samples taken at the exhaust of the vacuum system were analyzed by Fourier transform infrared spectroscopy. Clear evidence for NH3 formation was obtained from these measurements.

傅里叶变换红外检测在 Ar/H2/N2 气体混合物中运行的脉冲空心阴极放电中产生氨
在 Ar/H2/N2 气体混合物中运行带有铜镍阴极 (Cu50Ni50) 的空心阴极放电。直读光谱揭示了 NH 自由基的形成,NH 自由基是 NH3 形成的前体。离子质谱显示 NH3+ 和 NH4+ 离子的形成表明 NH3 的形成。通过傅里叶变换红外光谱分析在真空系统排气处采集的气体样本。从这些测量中获得了 NH3 形成的明确证据。
