Here, we prepared UiO-66-NH and employed a post-synthesis modification method for its functionalization with a β-cyclodextrin (β-CD) organic compound. The resulting composite was employed as a support for the heterogenization of the Pd NPs. Various techniques, including FT-IR, XRD, SEM, TEM, EDS, and elemental mapping, were used to characterize UiO-66-NH@β-CD/Pd, indicating its successful preparation. Three C-C coupling reactions, including the Suzuki, Heck, and Sonogashira coupling reactions, were promoted using the produced catalyst. As a result of the PSM, the proposed catalyst displays improved catalytic performance. In addition, the suggested catalyst was highly recyclable up to 6 times.
在此，我们制备了UiO-66-NH，并采用后合成修饰方法用β-环糊精（β-CD）有机化合物对其进行功能化。所得复合材料用作钯纳米颗粒（Pd NPs）多相化的载体。使用包括傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、能谱分析（EDS）和元素映射在内的各种技术对UiO-66-NH@β-CD/Pd进行表征，表明其制备成功。使用所制备的催化剂促进了包括铃木（Suzuki）、赫克（Heck）和宗贺ira（Sonogashira）偶联反应在内的三种碳-碳偶联反应。由于后合成修饰（PSM），所提出的催化剂表现出改进的催化性能。此外，所建议的催化剂可高度循环使用多达6次。
