查询词典 hydrogenate

LaNi〓 can be easily activated at room temperature and activated LaNi〓 possesses catalysing effect for the dissociation of H〓, which greatly reduces the energy barrier for dissociation of H〓. Hydrogen passed through LaNi〓 particles, then diffused into the crystal lattices of V、Nb and TiFe alloy and formed hydrogenate.

LaNi〓粒子在室温下很容易活化，活化后的LaNi〓具有了氢分子分解为氢原子的催化作用，降低了氢分子分解为氢原子所必须克服的势垒，氢通过LaNi〓粒子而进入V、Nb、TiFe合金晶格中，形成金属氢化物。

Further treatment of the Ru nanoparticles with chiral modifier (1S, 2S)-1, 2-diphenyl-1, 2-ethylene-diamirse (1S, 2S-DPEN and KOH in ionic liquid/i-PrOH mixed solvent resulted in a novel immobilized chiral catalyst which can asymmetrically hydrogenate acetophenone and its derivatives.

将此钌纳米粒子与(1S， 2S)-1，2-二苯基乙二胺（简称(1S， 2S)-DPEN）、KOH在离子液体／异丙醇介质中原位生成一种不对称加氢催化剂，用于催化苯乙酮及其衍生物的不对称加氢反应。

On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.

综合催化剂的表征和活性评价得出：当镍基催化剂上氧化镍以结晶态存在，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到丁二酸酐，丁二酸酐难以进一步加氢为γ-丁内酯；当镍基催化剂上氧化镍以簇团形式存在，与载体之间有适当的相互作用时，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到的丁二酸酐进一步加氢为γ-丁内酯；若催化剂上氧化镍既有结晶态又有簇团形式时，随二者含量比例不同而得到丁二酸酐和γ-丁内酯的混合物。
