Abstract The present work describes the synthesis of a new oxo-vanadium complex immobilized on SBA-15 nanostructure as an efficient catalyst for oxidation of sulfides and oxidative coupling of thiols. Characterization of the resultant AMPD@SBA-15 nanostructure was performed by various physico-chemical techniques such as Fourier transform infrared spectroscopy, transmission and scanning electron microscopies
摘要 本工作描述了固定在SBA-15纳米结构上的新型氧-钒配合物的合成,该配合物是硫化物氧化和硫醇氧化偶联的有效催化剂。所得的AMPD @ SBA-15纳米结构的表征是通过各种物理化学技术进行的,例如傅立叶变换红外光谱,透射和扫描电子显微镜,能量色散X射线光谱,电感耦合等离子体发射光谱,X射线衍射,热重分析和N 2吸附和解吸。所开发方法的结果带来了一些好处,例如使用可商购的,生态上无害的,操作简便的,廉价的和化学惰性的试剂。它显示出良好的反应时间,实用性和高效率,并且易于通过简单过滤从反应混合物中回收,并可以连续几个循环重复使用,而其催化活性没有明显变化。更重要的是,高效率,简单且廉价的方法,可商购的材料,易于分离以及环保的方法是当前采用的多相催化系统的几个优点。 图形概要
