In this paper, a novel catalyst is designed, synthesized and characterized based on the functionalization of magnetic iron oxide nanoparticles by terpyridine as a ligand for the immobilization of palladium. The catalyst is fully characterized by several characterization methods, including SEM, FTIR, DLS, VSM, EDS and XRD analysis. The results of the characterization techniques proved the successful synthesis of the desired catalyst. The applicability of the catalyst was evaluated in Heck and Suzuki reaction. The catalyst showed very good activity through the mentioned carbon-carbon bond formation reactions. The catalyst is magnetically recoverable and could be separated simply from the reaction media by an external magnet. The use of the catalyst in 10 sequential reactions did not show any significant loss in the activity of the catalyst.

本文基于三联吡啶作为固定钯的配体，在磁性氧化铁纳米颗粒的官能化基础上，设计，合成和表征了一种新型催化剂。该催化剂可通过几种表征方法充分表征，包括SEM，FTIR，DLS，VSM，EDS和XRD分析。表征技术的结果证明了所需催化剂的成功合成。在Heck和Suzuki反应中评估催化剂的适用性。通过所述的碳-碳键形成反应，催化剂显示出非常好的活性。催化剂是可磁性回收的，并且可以通过外部磁体简单地与反应介质分离。在10个连续反应中使用催化剂没有显示出催化剂活性的任何显着损失。
