Kaolin-loaded nano-iron catalyst and application thereof in catalyzing cross dehydrogenation coupling reaction

The invention provides a kaolin-loaded nano-iron catalyst and the application thereof in catalyzing cross dehydrogenation coupling reaction, and belongs to the technical field of catalysts. Accordingto the kaolin-loaded nano-iron catalyst provided in the invention, the kaolin-loaded nano-iron catalyst comprises a kaolin carrier and nano-iron loaded in the kaolin carrier. When the kaolin-loaded nano-iron catalyst provided by the invention is used for catalyzing cross dehydrogenation coupling reaction of cyclic ether C(sp3) H bonds and aromatic formic acid, activation and direct esterificationof the cyclic ether C(sp3) H bonds can be catalyzed, and a good catalytic effect is achieved. Meanwhile, the kaolin-loaded nano-iron catalyst provided by the invention is a heterogeneous catalyst, hasthe advantages of low cost, no toxicity and environmental sustainability, can be recycled for multiple times, and is very beneficial to application in modern industrial production. 本发明提供了一种高岭土负载纳米铁催化剂及其在催化交叉脱氢偶联反应中的应用，属于催化剂技术领
