  Picosecond real time study of the bimolecular reaction O(3P)+C2H4 and the unimolecular photodissociation of CH3CHO and H2CO

  摘要：

  The bimolecular reaction of O(3P) with ethylene and the unimolecular photodissociation of acetaldehyde and formaldehyde have been studied using a picosecond pump/probe technique. The bimolecular reaction was initiated in a van der Waals dimer precursor, C2H4⋅NO2, and the evolution of the vinoxy radical product monitored by laser-induced fluorescence. The NO2 constituent of the complex was photodissociated at 266 nm. The triplet oxygen atom then attacks a carbon atom of C2H4 to form a triplet diradical (CH2CH2O) which subsequently dissociates to vinoxy (CH2CHO) and H. The rise time of vinoxy radical production was measured to be 217 (+75−25) ps. RRKM theory was applied and a late high exit barrier was invoked in order to fit the measured rise time. The structure and binding energy of the van der Waals complex have been modeled using Lennard-Jones type potentials and the results were compared with other systems. The unimolecular side of the potential energy surfaces of this reaction has been investigated by photodissociating acetaldehyde at the same pump energy of 266 nm. The resulting photoproducts, acetyl radical (CH3CO) and formyl radical (HCO), have been monitored by resonance enhanced multiphoton ionization (REMPI) combined with a time-of-flight mass spectrometer. The similarity in the measured evolution times of both radicals indicates the same photodissociation pathway of the parent molecule. The photodissociation rate of acetaldehyde is estimated from RRKM theory to be very fast (3×1012 s−1). The T1←S1 intersystem crossing (ISC) rate is found to be the rate determining step to photodissociation and increases with energy. The REMPI mechanism for the production of CH3CO+ is proposed to be the same as that of HCO+(2+1). The HCO product from the photodissociation of formaldehyde at 266 nm reveals a faster T1←S1 ISC rate than in acetaldehyde.

Although the chemistry accompanying the intercalation processes appears complex (small losses of phosphorus, appearance of phosphate, and thiophosphate PS43−species), the catalytic efficiency of the intercalates is correlated to their ability to be reduced in depth when

  通过使该化合物与硫化钠水溶液反应并随后进行阳离子交换或聚合物插入，已经合成了几种层状NiPS 3的插层。研究了这些插层对二价氧将硫化物离子氧化为元素硫的催化效率。结果表明，这些插层比原始NiPS 3具有更高的效率（更高的反应速率，更小的活化能，任何诱导期的抑制）。主要通过Ni，P和S原子的XPS研究了插层的电子结构。尽管插层过程伴随的化学过程看起来很复杂（磷的少量流失，磷酸盐的出现和硫代磷酸盐PS 4 3-）时，嵌入物的催化效率与其在与硫化钠水溶液接触时深度降低的能力有关。我们的结果与先前提出的基于与宿主晶格的氧化还原修饰相关的钠离子的嵌入/脱嵌过程序列的催化机理相一致。

  polyethylene-oxide (PEO) have been confined by intercalation within the galleries of an insulating, inorganic layered solid CdPS3. The dc conductivity of this confined polymer electrolyte Cd0.75PS3Li0.5(PEO) displays a distinct change in the mechanism of conduction with temperature, exhibiting a crossover from an Arrhenius temperature dependence at low temperatures to an non-Arrhenius, Vogel–Tamman–Fulcher behavior

  The complexes involving PEO and perfluorosulphonimide (TFSI) salts of divalent metals (lead, nickel and copper) have been studied. Encouraging results have been obtained with the TFSI anion as the conductivities are markedly higher than those involving the same cations with other anions. In addition, these complexes are generally entirely amorphous for compositions n ≤ 12 above room temperature. The

  摘要：与其他二价阳离子盐的 PEO 溶液相比，具有优化成分的聚环氧乙烷 (PEO) 基卤化锌 (II) 电解质表现出相当高的电导率。化学扩散研究清楚地表明，Zn(II) 和 Br(-I) 都是可移动的。Zn(H) 阳离子似乎有两种形式，一种与醚氧相关，另一种与阴离子相关。前者的移动性应该低于后者，这是合理的。遗憾的是，使用电化学技术对电荷载流子的转移数和扩散系数进行定量测量证明是困难的。其他测量发现，完全无定形电解质的 Tg 值随 (Zn) (O) 的摩尔比线性增加，表明 Zn(II) 阳离子与 PEO 链中的醚氧相互作用以形成链间和/或链内交联。聚（环氧乙烷）、Zn（II）卤化物电解质、二价阳离子盐、阳离子、阴离子、摩尔比、转移数、扩散系数、电荷载流子、链间和链内交联。
