摘要:
采用水热法制备Fe3O4纳米粒子,通过St?ber法在其表面均匀包覆一层SiO2,利用3-巯丙基三甲氧基硅烷对包硅磁性纳米粒子进行巯基修饰,将纳米金与带巯基的磁性纳米粒子结合制得磁性纳米催化剂。利用X射线衍射仪、透射电子显微镜、傅里叶红外分析仪对磁性纳米粒子进行表征,并研究了磁性纳米催化剂在不同条件下对对硝基苯酚还原反应的催化效率。结果表明:负载纳米金的磁性纳米催化剂平均粒径为323 nm。在实验条件下,催化对硝基苯酚还原反应可在6 min内完成,利用磁铁即可实现分离回收,重复利用8次催化效率仍在92%以上。
Abstract:
Iron oxide nanoparticles were prepared by hydrothermal method,and were coated with silica layer by a St?ber process. The silica-coated magnetic nanoparticles were modified with thiol groups with 3-mercaptopropyltrimethoxysilane,and gold nanoparticles were then immobilized on the surface to fabricate the magnetic nanocatalyst. The prepared magnetic catalyst was characterized by X-ray diffraction,transmission electron microscopy and Fourier transform infrared spectroscopy,and its catalytic performance was investigated through the reduction of p-nitrophenol. The results showed that the average diameter of magnetic nanocatalyst was about 323 nm. The reduction of p-nitrophenol was completed in 6 min under the optimal experimental conditions. The catalyst was easily recycled with a magnet, and its catalytic efficiency kept higher than 92% after 8 times of recycling use.
