本文研究了大气压旋转滑动弧等离子体在氮气中裂解水制氢。输入H2O浓度和总流速对等离子体水裂解过程的性能的影响（例如，考察了H2和O2产率、H2产率和H2的能量产率。N2对H2O裂解和H2产生过程显示出明显的促进作用，这是由于受激发的N2物种的反应[例如，电子激发的亚稳态N2（A）]与H2O分子。最大H2产生速率达到41.3 μ mol-1，这远高于其他典型的非热等离子体（例如，~0.2 μ mol − 1（对于介质阻挡放电）。光发射诊断表明，除了在纯N2光谱中观察到的NO、N2和N2+外，在H2O/N2光谱中也出现了强OH和NH发射线。OH自由基被认为是一个关键的中间物种，可以有助于形成H2，O2和H2 O2。随着H_2O浓度的增加，OH的强度不断增强。在N2等离子体中加入1%（mol/mol）的H2O后，N2+的转动温度从2875 ± 125 K急剧下降到1725 ± 25 K。
In this study, hydrogen production from water splitting in N2using an atmospheric pressure rotating gliding arc plasma was investigated. The effect of input H2O concentration and total flow rate on the performance of the plasma water splitting process (e.g., H2and O2yield, H2production rate, and energy yield of H2) was investigated. N2showed a pronouncedly facilitating effect on the H2O splitting and H2production process due to the reactions of the excited N2species [e.g., electronically excited metastable N2(A)] with the H2O molecules. The maximum H2production rate reached up to 41.3 μmols−1, which is much higher than that of other typical non-thermal plasmas (e.g., ~0.2 μmols−1for a dielectric barrier discharge). Optical emission diagnostics has shown that in addition to the NO, N2, and N2+that were observed in the pure N2spectra, strong OH and NH emission lines also appeared in the H2O/N2spectra. OH radical is considered as a key intermediate species that could contribute to the formation of H2, O2, and H2O2. The increase of the H2O concentration could lead to a continuous enhancement of the OH intensity. The rotational temperature of N2+dropped drastically from 2875 ± 125 to 1725 ± 25 K with the addition of 1 % (mol/mol) H2O into the N2plasma.
