NOVELTY - Low-migration ferrocene-based functionalized graphene oxide combustion catalyst, prepared by using graphene oxide, copper nitrate trihydrate, ferrocene formaldehyde and amino derivatives as reaction raw materials, deionized water or absolute ethanol as a reaction solvent and anhydrous sodium sulfate as a catalyst through a coordination reaction and a Schiff base reaction. USE - The low-migration ferrocene-based functionalized graphene oxide combustion catalyst is useful in composite solid propellants. ADVANTAGE - The low-migration ferrocene-based functionalized graphene oxide combustion catalyst: has good thermal stability under natural conditions which does not easily volatilize; and can improve its anti-migration ability in the propellant and the combustion performance of solid propellants thus its low mobility also ensures the stability of the entire solid propellant during storage and reduce the thermal decomposition temperature of ammonium perchlorate thus promote its rapid decomposition and releases more heat in a short time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing low-migration ferrocene-based functionalized graphene oxide combustion catalyst, comprising (i) dispersing the oxidized graphene ultrasonically in the deionized water to obtain the graphene dispersion, dissolving the trihydrate copper nitrate in the deionized water to obtain the copper nitrate trihydrate solution, stirring while injecting the copper nitrate trihydrate solution into the dispersion graphene, heating for coordination reaction by ultrasonic wave, centrifuging and washing to obtain the first product; (ii) dissolving the ferrocene formaldehyde in anhydrous ethanol to obtain ferrocene formaldehyde solution, dissolving the amino derivative in anhydrous ethanol to obtain amino derivative the ferrocene formaldehyde solution is injected into the amino derivative solution, injecting the ferrocene formaldehyde solution into the amino derivative solution to carry out the Schiff base reaction, adding an intermediate catalyst, heating and performing suction filtration, rotary evaporation, redissolving and washing in sequence to obtain the second product; and (iii) dispersing the first product in dehydrated alcohol to obtain the first product dispersion liquid, dissolving the second product in absolute ethanol to obtain the second product solution, injecting the second product solution into the first product dispersion, heating, centrifuging to wash, collecting the washed precipitate and drying in vacuum.
