Palladium nanoparticles supported on MOF-5 (Pd/MOF-5), have been prepared by a chemical method at room temperature. MOF-5 and Pd/MOF-5 were characterized by X-ray diffraction, N2 sorption, thermogravimetric analysis, scanning electron microscopy, and transmission electron microscopy. The catalyst consists of highly dispersed palladium nanoparticles (about 3–6 nm) on MOF-5 with a high surface area (533 m2/g)
负载在MOF-5(Pd / MOF-5)上的钯纳米粒子已通过化学方法在室温下制备。MOF-5和Pd / MOF-5通过X射线衍射,N 2吸附,热重分析,扫描电子显微镜和透射电子显微镜表征。该催化剂由在MOF-5上具有高表面积(533 m 2 / g)的高度分散的钯纳米颗粒(约3–6 nm )组成。对于芳基碘化物和末端乙炔之间的Sonogashira偶联反应,它表现出有效的催化活性,而无需配体和铜的辅助。
