In this work, a novel core-shell structured magnetic CoO@mSiO nanocomposite supported ionic liquid/palladium (CoO@mSiO/IL-Pd) is synthesized and its structure is characterized by using PXRD, EDX, FT-IR, SEM, TEM, TGA and VSM. This magnetic material was prepared through coating of mesoporous silica shell on magnetic cobalt oxide nanoparticles followed by chemical immobilization of ionic liquid/Pd complex. The CoO@mSiO/IL-Pd nanocomposite was used as an efficient and powerful catalyst for the reduction of nitrobenzenes. The excellent yield of the products, short reaction time and easy catalyst recoverability with no significant decrease in activity showed the high efficiency and stability of the designed nanocomposite under applied conditions.
在本工作中,合成了一种新型的核壳结构磁性CoO@mSiO纳米复合材料负载离子液体/钯(CoO@mSiO/IL-Pd),并通过PXRD、EDX、FT-IR、SEM、TEM、TGA和VSM对其结构进行了表征。这种磁性材料是通过在磁性氧化钴纳米颗粒上包覆介孔二氧化硅壳层,然后化学固定离子液体/Pd络合物制备而成。CoO@mSiO/IL-Pd纳米复合材料被用作还原硝基苯的高效且强大的催化剂。产物的优异产率、较短的反应时间以及催化剂易于回收且活性无显著降低,表明了所设计的纳米复合材料在应用条件下具有高效性和稳定性。
