本工作通过在介孔SBA-15分子筛表面负载钴络合物制备了一种新型的绿色催化剂，并用热重分析、扫描电子显微镜、红外光谱、能谱、电感耦合等离子体、比表面积和X-射线衍射图等方法对其进行了表征。该介孔材料是一种高效、绿色的界面催化剂，用于氧化反应和多氢喹啉衍生物的合成。反应时间短，产率高。此外，所制备的催化剂可以使用六次，而其催化活性和钴浸出不会有明显的下降。(C)2018爱思唯尔有限公司。保留所有权利。
In this work, a green and novel catalyst was prepared through immobilization of cobalt complex on the surface of mesostructured SBA-15 and characterized by TGA, SEM, FT-IR, EDX, ICP, BET and X-ray mapping analytical methods. This mesostructural material was used as an efficient and green interphase catalyst for the oxidation reactions and synthesis of polyhydroquinoline derivatives. All reactions were performed in short times and good yields. Moreover, the prepared catalyst could be used up to six runs without significant degradation in its catalytic activity or cobalt leaching.
