  Gas-phase reactions between hydrocarbons and metal oxides: the aluminum monoxide + methane reaction from 590 to 1380 K

  摘要：

  A recent ab inito study suggested that gaseous metal oxides can directly abstract H atoms from hydrocarbons, but with considerable barriers. To try to confirm the occurrence of such reactions, the title reaction has been studied in a high-temperature fast-flow reactor. The data are well described by the fitting expression k(590-1380 K) = 9.6 X 10(-39)(T/K)7.96 exp(2468 K/T) cm3 Molecule-1 s-1, with 2sigma precision limits varying with temperature from +/- 4% to +/- 12%. The corresponding 2sigma accuracy limits are about +/- 25%. Comparison of this result to further ab initio and conventional transition-state theory calculations suggests that direct abstraction indeed can occur at the higher temperatures but that one or more other channels, possibly involving AlO insertion into a C-H bond, dominate in the initial attack step. The potential implications of this work for catalytic conversion of methane to higher hydrocarbons are considered.

  This paper reports an investigation of the electronic structures of the Group IIIA metal atom hydration reaction intermediates (M⋯OH2adducts) and their subsequent photolysis products (HMOH, MOH and MO) where M = Al, Ga and In. The metal–water interaction in the adduct is sufficiently strong to perturb the electronic structure of the metal atom; consequently, one observes a unique band structure for

  本文报告了IIIA组金属原子水合反应中间体（M⋯OH 2加合物）及其后续光解产物（HMOH，MOH和MO）的电子结构的研究，其中M = Al，Ga和In。加合物中的金属与水的相互作用足够强，足以扰乱金属原子的电子结构。因此，人们观察到加合物具有独特的能带结构，该加合物从金属的原子共振跃迁中发生了红移。提出了分子轨道和电子状态间的相关性。

  The temperature and pressure dependence of the rate constant for the reaction Al+O2 has been measured by observing both Al disappearance and AlO appearance. No pressure dependence is observed from 10 to 100 Torr total pressure of Ar at room temperature. Over the range 298–1083 K, a fit to the measured data yields the expression k(T) = (1.62±0.13) × 10−10 cm3 s−1 exp[(−0.16±0.08) kcal mol−1/RT].

  通过观察Al的消失和AlO的出现来测量反应Al + O 2的速率常数的温度和压力依赖性。在室温下，从Ar的10至100 Torr总压力中未观察到压力依赖性。在298–1083 K范围内，对测量数据的拟合得出表达式k（T）=（1.62±0.13）×10 -10 cm 3 s -1 exp [（-0.16±0.08）kcal mol -1 / RT ]。

  We have used laser‐induced fluorescence to measure the energy distributions of Al atoms and AlO molecules produced by excimer laser ablation of Al2O3. Excimer laser fluences close to the threshold for ablation were used to minimize the effects of gas phase collisions. The kinetic energies of both species were high, ∼4 eV for Al and ∼1 eV for AlO, but the AlO rotational and vibrational energies were

  我们使用激光诱导荧光来测量由准分子激光烧蚀 Al2O3 产生的 Al 原子和 AlO 分子的能量分布。使用接近烧蚀阈值的准分子激光能量密度来最小化气相碰撞的影响。两种物质的动能都很高，Al 约为 4 eV，Al2O 约为 1 eV，但 Al2O 的旋转能和振动能非常低，对应的温度约为 600 K。这些结果排除了热汽化并提供了间接支持电子消融机制。
