Abstract

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.

通过傅立叶变换红外线检测在 Ar/H2/N2 混合气体中运行的脉冲空心阴极放电中的氨生成情况

采用铜镍阴极（Cu50Ni50）的空心阴极放电装置在 Ar/H2/N2 混合气体中运行。光学发射光谱显示形成了 NH 自由基，这些自由基是 NH3 形成的前体。离子质谱法显示，NH3+ 和 NH4+ 离子的形成表明 NH3 的形成。在真空系统排气口采集的气体样本通过傅立叶变换红外光谱进行了分析。这些测量结果清楚地证明了 NH3 的形成。
