Problems solved by technology

[0006] At present, the main processing technology that graphene oxide is used for the catalysis of ammonium perchlorate is: 1. Mix graphene oxide and ammonium perchlorate in a mixer. Since no surface treatment is carried out in this method, graphene oxide is easy to Agglomeration occurs, reducing the catalytic effect; 2. Attaching ammonium perchlorate particles to the surface of graphene oxide sheets, this method increases the contact area between ammonium perchlorate and graphene oxide, but because the sheets are independent of each other , thus limiting the conduction of heat, which limits the further improvement of catalytic performance; 3. Depositing graphene oxide on the surface of ammonium perchlorate particles, this method also does not form a good heat conduction path, which limits the improvement of thermal decomposition catalytic performance
