    Energy partitioning in two kinds of NO molecules generated from the reaction of O(1D) with N2O: Vibrational state distributions of “new” and “old” NO’s
    摘要:
    The reaction of O(1D) with N2O produces two kinds of NO molecules, the “old” one which originally exists in N2O and the “new” one which includes the attacking O atom. Using the isotopically labeled reagent, we determined the vibrational state distributions of these NO’s (X 2Π; v=0–17) separately. To obtain the distributions, two types of experiments were performed with the laser-induced fluorescence (LIF) technique via the NO A←X and B←X transitions. First, the relative populations of NO molecules (the sum of the two kinds of NO’s) in v=0–11 levels were measured with unlabeled reagents. Then, isotopically labeled reaction, O18(D1)+N216O→N18O+N16O, was utilized to determine the relative ratio between the two kinds of NO’s in the vibrational levels of v=0–5 and 12–15. Combining the above results with previously determined vibrational state distribution of NO in high vibrational levels (v=11–17) [J. Chem. Soc., Faraday Trans. 94, 1575 (1998)], we were able to obtain a complete set of vibrational state distributions. It was found that the old NO dominantly populated in v=0 and 1 whereas the new NO extended its population toward higher vibrational levels (v=4–15). However, in high vibrational levels, the old NO still have a considerable population due to the rapid energy transfer to the old NO. The observed efficient energy transfer to the old NO is attributed to the absence of light atoms in the present reacting system. Compared with the system including hydrogen atoms, the state density and the momentum coupling among the vibrational modes are much larger and accelerate the energy redistribution in spite of the short lifetime.

    摘要:
    一个复杂的动力学和物理化学方法:温度编程的表面反应(TPSR),脉冲NH 3或NH 3 / 16 Ô 2(18 Ò 2)的反应混合物,和红外和光电子光谱,被用于的高选择性支持表征锰-铋氧化物催化剂以及用于氨氧化机理的研究。氨氧化被证明是通过在晶格氧的参与下催化剂表面的交替还原和再氧化而进行的。NH 3通过夺取氢原子与弱键合的氧物种相互作用,形成吸附的[N]物种,它们位于Mn 2+上和Mn δ +(2 < δ <3)。氧化度不同的锰离子(Mn 3+(Mn 4+)和Mnδ +)用作催化剂表面的活性中心。建立了对N 2 O的选择性与Mn 3+(Mn 4+)态的锰含量之间的相关性。氧化铋通过增加地下氧气的数量,迁移率和热稳定性起重要作用。根据实验结果提出了反应动力学方案。TPSR数据的数值模拟证实了所提出反应机制的可靠性。

  • Mechanism of O2 Desorption during N2O Decomposition on an Oxidized Rh/USY Catalyst

    Pulsed N2O decomposition on a reduced or oxidized Rh/USY catalyst has been carried out to study the dependence of oxygen coverage (θo) on activity and to study the mechanism of O2 desorption using an isotopic tracer technique. Decomposition activity decreased to the minimum (formation of only N2) at θo=0.5, but increased with increasing coverage (θo>0.5), and finally high activity with steady-state
    脉冲Ñ 2上的还原或氧化的Rh / USY催化剂O分解已进行了研究氧气覆盖的依赖性(θ ö)上的活动,并研究的O机构2使用同位素示踪技术解吸。分解活性降低至最小(形成的n只有2在θ)Ô = 0.5,但随着覆盖率提高(θ ö > 0.5),以及与稳态ö最后高活性2被获得以高θ生产Ô(> 1.2)。在同位素研究中,在低温(220–240°C)下,将N 2 16 O脉冲到18 O /氧化的Rh催化剂上,然后将O解吸通过质谱监测2个分子。解吸的氧气中的18 O分数与表面氧气上的18 O分数几乎相同。结果表明,O 2的解吸不是通过Eley-Rideal机理进行的,而是通过Langmuir-Hinshelwood机理进行的,即通过吸收的氧的复合使二氧解吸。另一方面,He中的O 2 -TPD测量表明,氧从Rh催化剂中解吸发生在高得多的温度下。因此,提出了在低温下N 2 O分解期间发生O 2的反应辅助解吸的问题。
