The invention discloses a preparation method and application of an aluminum monatomic catalyst. The preparation method comprises the following steps of: polymerizing styrene in an inner hole of an aluminum-based metal organic framework material adsorbing styrene under a heating condition, carrying out carbonization and fluorination, and then washing a fluorination product with hot ammonia water toobtain the aluminum monoatomic catalyst. The catalyst can be applied as a catalyst to dehydrohalogenation or fluorine-chlorine exchange reaction. The aluminum monatomic catalyst prepared by the invention has the advantages of simple preparation method, large specific surface area, high effective utilization rate of aluminum atoms, high catalytic performance, long service life and great application prospect. 一种铝单原子催化剂的制备方法及其应用。制备方法是将吸附苯乙烯的铝基金属有机框架材料在加热条件下使苯乙烯在铝基金属有机框架材料内孔内聚合，然后再进行碳化和氟化，之后再用热的氨水洗涤氟化产物，得到在铝单原子催化剂，且该催化剂可作为催化剂在脱卤化氢或氟氯交换反应中进行应用。本发明制备的铝单原子催化剂，制备方法简单，比表面积大，铝原子的有效利用率高，催化性能高，使用寿命长，极具应用前景。
