Heterogeneous catalysts for the hydrogenation of unsaturated hydrocarbons have been synthesized on the basis of palladium and platinum nanoparticles immobilized in pores of mesoporous aromatic frameworks, which represent a new class of carbon supports with a diamond-like ordered structure. The resulting materials have been characterized by transmission electron microscopy, IR spectroscopy, and NMR
基于固定在介孔芳族骨架孔中的钯和铂纳米粒子,合成了用于不饱和烃氢化的非均相催化剂,这代表了一类具有菱形有序结构的新型碳载体。所得材料已通过透射电子显微镜,IR光谱和NMR光谱表征。已经表明,氢化反应中的催化剂活性取决于底物分子的大小和纳米颗粒表面上的吸附性。在60和80°C的温度和1.0和3.0 MPa的压力下氢化许多不饱和化合物的过程中,已经研究了催化活性。
