This report contains the procedure implemented in the preparation of FeO@SiO/isoniazide/Pd as a novel magnetic nanocatalyst, in which isoniazide groups are utilized (as linkers) to secure palladium nanoparticles (Pd NPs) to the FeO exterior without agglomeration. The resultant catalyst was characterized through performing transmission electron microscopy (TEM), scanning electron microscopy (SEM), wavelength-dispersive X-ray spectroscopy (WDX), X-ray powder diffraction (XRD), Fourier transform infrared (FTIR), inductively coupled plasma (ICP), Energy-dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM) and X-ray photoelectron spectroscopy (XPS). The catalytic behavior of FeO@SiO/isoniazide/Pd was investigated to synthesis of biaryl compounds by Suzuki coupling reactions. Interestingly, the novel catalyst was able to be recovered and recycled six times without any noticeable loss in activity.
本报告介绍了制备 FeO@SiO/异烟肼/Pd 新型磁性纳米催化剂的过程，其中利用异烟肼基团（作为连接剂）将钯纳米粒子（Pd NPs）固定在 FeO 外部，防止团聚。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、波长色散 X 射线能谱（WDX）、X 射线粉末衍射（XRD）、傅里叶变换红外（FTIR）、电感耦合等离子体（ICP）、能谱（EDS）、振动样品磁强计（VSM）和 X 射线光电子能谱（XPS）对所得催化剂进行了表征。研究了 FeO@SiO/异烟肼/Pd 的催化行为，用于Suzuki 偶联反应合成联苯类化合物。有趣的是，新型催化剂在六次回收和循环使用过程中，活性没有明显下降。
