  Catalytic reduction of N2O by various hydrocarbons over Fe-ZSM-5: nature and reactivity of carbonaceous deposits

  摘要：

  The catalytic reduction of dinitrogen monoxide (N2O) by various hydrocarbons (CH4, C2H4, C1H6, C3H6, C3H8) in the absence and presence of 0, has been studied over Fe-ZSM-5 catalysts. These hydrocarbon reductants are phenomenologically divided into three groups, namely CH4, C3H6, and others (C2H4, C2H6, C3H8), referred to as the CH4 group. Two types of carbonaceous deposits (Calpha, Cbeta) are formed on Fe-ZSM-5 during the reduction of N2O by C-2 and C-3 hydrocarbons in the absence of O-2. In both cases of C2H4 and C3H6, the catalytic activity of Fe-ZSM-5 decreases with an increase in the amount of Calpha, while it is not affected by the presence of Cbeta. The Calpha species is formed on Fe sites and the Cbeta is mainly accumulated on the support. The formation of these carbonaceous deposits from the C2H4 group is suppressed by the presence of O-2 in the feed gas, and this promotes the catalytic reduction of N2O. The amount and the chemical nature of Calpha formed in the cases of the C2H4 group and C3H6 are similar, while those of Cbeta are significantly different. The reactivity of Cbeta with O-2 should be different and this may be responsible for the difference in the effects of O-2 addition on the reduction of N2O between the C2H4 group and C3H6. In the case of CH4. a high stable conversion of NO is obtained irrespective of the presence and absence of O-2 because the carbonaceous deposits are scarcely accumulated on the catalyst.

  Fe +和FeO +与C 2 H 2，C 2 H 4和C 2 H 6的反应：温度依赖性动力学

  摘要：

  我们给出了Fe +和FeO +与C 2 H 2，C 2 H 4和C 2 H 6从170到700 K的反应的第一温度依赖性速率常数和支化比。观察到Fe +仅反应通过与三种碳氢化合物结合使用，温度依赖性为T –2至T –3。FeO +与C 2 H 2和C 2 H 4反应在整个温度范围内的碰撞速率下，它们各自的产物分支显示出相似的温度依赖性。相反，与乙烷的反应在170 K时发生碰撞，但随T –0.5的变化而变化，而产物支链随温度基本保持平坦。反应性的这些变化是根据已公布的反应性电势面进行讨论的。还讨论了Fe +作为对三种烃的氧转移催化剂的有效性。

  Copper-nitrito and -nitro isomers, [Cu(ONO)(tpa)]PF6 and [Cu(NO2)(tpa)]PF6 (tpa = tris[(2-pyridyl)methyl]amine) were isolated and the molecular structures were determined by X-ray analysis. [Cu(ONO)(tpa)]PF6 (C18H18N5O2PF6Cu) crystallizes in the monoclinic space group P21/a with a = 13.374(2), b = 14.033(2), c = 13.455(2) Å, β = 119.10(1)°, V = 2206.5(6) Å3, and Z = 4. [Cu(NO2)(tpa)]PF6 (C18H18N5O2PF6Cu) crystallizes in the orthorhombic space group I/ba2 with a = 16.718(3), b = 17.554(3), c = 14.785(3) Å, V = 4338(1) Å3, and Z = 8. Those nitrito- and nitro-complexes exist as an equilibrium mixture in solutions. Electrochemical reduction of NO2− in the presence of [Cu(H2O)(tpa)](ClO4)2 at −0.4 V in H2O (pH 7.0) catalytically produced N2O with concomitant evolution of a small amount of NO via the nitro and nitrito adducts.

  using strong Lewis acids E(C6F5)3 (E=B or Al) in combination with metallocenes. In the case of B(C6F5)3, electron transfer to N2O required a powerful reducing agent such as Cp*2Co (Cp*=pentamethylcyclopentadienyl). In the presence of Al(C6F5)3, on the other hand, the reactions could be performed with weaker reducing agents such as Cp*2Fe or Cp2Fe (Cp=cyclopentadienyl). The Lewis acid‐mediated electron

  使用强路易斯酸E（C 6 F 5）3（E = B或Al）结合茂金属可实现一氧化二氮（N 2 O）的单电子还原。在B（C 6 F 5）3的情况下，电子转移到N 2 O需要强力的还原剂，例如Cp * 2 Co（Cp * =五甲基环戊二烯基）。另一方面，在存在Al（C 6 F 5）3的情况下，可以用较弱的还原剂如Cp * 2 Fe或Cp 2进行反应。Fe（Cp ＝环戊二烯基）。路易斯酸介导的电子从茂金属转移到N 2 O导致N-O键断裂，生成N 2和氧基自由基阴离子[OE（C 6 F 5）3 ] ⋅-。后者是高反应性的，并参与CH活化反应。可以通过添加Gomberg二聚体来捕获自由基，该Gomberg二聚体是三苯甲基自由基的来源。
