摘要
In this project, the main aim is the design and present a novel and unique heterogeneous nanocatalyst based on a metal–organic framework/covalently sulfonated magnetic SBA‐15 mesoporous silica composite with the emphasis on promoting clean and green synthetic transformations and increasing the catalytic properties. In more detail, initially, SBA‐15 containing magnetic nanoparticles was functionalized by a 1,3‐propane sultone ligand. In the next step, the functionalized mesoporous substrate was used as a scaffold for the growth and synthesis of the zeolite imidazolate framework‐8 (ZIF‐8) crystals. The obtained composite was further applied as a suitable support for the immobilization of Pd nanoparticles via a post‐modification procedure and the generation of heterogeneous catalysts. The prepared Fe 3 O 4 @SBA‐15‐SO 3 H@ZIF‐8@Pd was incorporated as a heterogeneous and green catalyst in the Suzuki coupling reaction in the natural deep eutectic solvent with efficient recyclability.
