used as a support for the uniform dispersion of ruthenium nanoparticles having an average particle size of ∼5 nm. The obtained nanocomposite, MCM-41-Ru, was characterized using inductively coupled plasma, transmission electron microscopy, energy dispersive X-ray analysis, X-ray diffraction, and BET surface area measurements. The material was employed as an efficient and recyclable catalyst in the ultrasound-assisted
摘要 介孔 MCM-41 被用作均匀分散平均粒径为 5 nm 的钌纳米颗粒的载体。获得的纳米复合材料 MCM-41-Ru 使用电感耦合等离子体、透射电子显微镜、能量色散 X 射线分析、X 射线衍射和 BET 表面积测量进行表征。该材料在芳烃的超声辅助氧化中用作有效且可回收的催化剂。据观察,在 MCM-41-Ru 纳米粒子的存在下,超声辐照与作为氧化剂的 KBrO 3 组合加速氧化反应,以良好的产率提供所需的产物。回收的催化剂在连续运行中保持活性,其活性位点的性质不断变化。
