Embodiment 1

[0023] 4mmol Co(NO 3 ) 2 ·6H 2 O, 2mmol Cu(NO 3 ) 2 ·6H 2 O and 12 mmol urea were dissolved in 50 mL of polyethylene glycol 200 (PEG-200) to form a transparent pink solution, then the above mixture solution was transferred to a stainless steel reaction kettle containing a polytetrafluoroethylene liner, and reacted at 180 °C 12 hours. After natural cooling to room temperature, the resulting solid was filtered, washed thoroughly with deionized water and ethanol three times, and dried in an oven at 60 °C to obtain nanoflower-like CuCo 2 o 4 product.

Description

technical field [0001] The invention relates to a preparation method and application of an ammonium perchlorate thermal decomposition catalytic material, and belongs to the technical field of nanometer material preparation and energetic materials. Background technique [0002] Due to their special properties such as large specific surface area and high surface activity, nanomaterials are widely used in the field of catalysis, such as photoelectric catalysis, biocatalysis and organic reactions. In recent years, more and more studies have reported the use of nanomaterials as combustion catalysts for solid propellants. Ammonium perchlorate (AP) is an oxidant and high-energy component widely used in composite solid rocket propellants, and it occupies a large proportion in the propellant, which can reach 65% to 90%. The thermal decomposition performance of AP directly affects the overall combustion performance of solid propellants. Therefore, it is of great significance to stud...
