本文介绍了第一个使用多孔芳族骨架作为硫化物催化剂载体用于芳烃加氢的例子。以介孔类金刚石结构的芳香族骨架为载体，通过原位分解[（n-Bu）（4）N]（2）[Ni（MeS 4）（2）]（Me = W，Mo）配合物，合成了负载型Ni-W和Ni-Mo硫化物.结果表明，最高的萘转化率的情况下，实现了额外的硫化与硫。反应结束后，用X射线光电子能谱和高分辨透射电子显微镜对催化剂进行了表征。以萘为模型底物研究了合成催化剂的活性。本研究中所用的材料在萘的加氢反应中基本上是活性的，在加氢裂化反应中是轻微的。
This paper describes the first example of using porous aromatic frameworks as supports for sulfide catalysts for the hydrogenation of aromatic hydrocarbons. The synthesis of bimetallic Ni-W and Ni-Mo sulfides was performed by in situ decomposition of [(n-Bu)(4)N](2)[Ni(MeS4)(2)] (Me = W, Mo) complexes, supported on mesoporous aromatic framework with a diamond-like structure. It is shown that the highest naphthalene conversions were achieved in the case of additional sulfidation with sulfur. After the reaction, catalysts were characterized by X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy. The activity of synthesized catalysts has been studied using naphthalene as a model substrate. The materials used in this study were substantially active in hydrogenation and slightly in hydrocracking of naphthalene.
