  Hydride and ammonia dispersion of metals

  摘要：

  Chemical (hydride and ammonia) dispergation of Group II-V metals induced by hydrogen and ammonia in the temperature range of 100-500A degrees C at a pressure of 0.5-2.0 MPa was studied. The phase transitions in the M-H-2 and M-NH3 systems were investigated and conditions for metal hydride and nitride formation as highly dispersed powders were identified. The characteristic features of metal dispergation under the action of hydrogen and ammonia and the degrees of dispersity of the obtained powders were compared.

  The reaction of V atoms with H2O and various concentrations of C2D4 in argon has been investigated by matrix isolation infrared (IR) spectroscopy. Both C2D6 and CD2H-CD2H are observed as the major products of a set of parallel processes involving hydrogenation of ethene where the formal source of hydrogen is either C2D4 or H2O. Portions of the IR spectrum of CD2H-CD2H isolated in an argon matrix are

  V原子与H2O和氩气中各种浓度的C2D4的反应已通过基质隔离红外（IR）光谱进行了研究。观察到C2D6和CD2H-CD2H都是涉及乙烯加氢的一系列平行过程的主要产物，其中氢的正式来源为C2D4或H2O。首次观察到在氩气基质中分离出的CD2H-CD2H的红外光谱的一部分。对于涉及低浓度C2D4的实验，用波长> 455 nm的光照射基质会形成VH2，而对乙烯氢化的观察有限。据信，H 2的来源是由于在基质沉积过程中，从OV-VH物种中分子氢的光消除作用，其中OV作为另外的产物。在低乙烯条件下，OV与H2在基质中的有效结合被认为是OVH2的来源。在我们的条件下没有观察到VD2形成的证据。在较高的C2D4浓度下，VH2的形成受到抑制，而乙烯氢化的产物则最大化。提出了与H2消除竞争的第二种方法，其中HO-VH与C2D4反应。提出了将V原子插入水的OH键中或将V原子光诱导插入C2D4的CD键中的并行反应

• Reactions of vanadium and titanium with molecular hydrogen in krypton and argon matrixes at 12 K

  Vanadium and titanium have been codeposited with molecular hydrogen in Kr and Ar matrices at 12 K. Both metals show photoreactivity toward molecular hydrogen and undergo insertion into the H-H bond to form metal dihydrides, MH2 (M = Ti, V). The symmetric and antisymmetric stretching frequencies have been detected for both VH2 and TiH2. The bond angles for TiH2 and VH2 were estimated to be 145 +/- 5-degrees and 127 +/- 5-degrees, respectively. The stretching force constants for TiH2 and VH2 were calculated to be 1.29 and 1.44 mdyn/angstrom, respectively. Vanadium monohydride was also identified as a photolysis product. Vibrational band assignments have also been made for TiH4. Small titanium clusters, Ti(n) were isolated and shown to react spontaneously with H-2.
