▎ 摘　　要

NOVELTY - Sub-nano cerium oxide/bismuth ferrite/reduced graphene oxide complex comprises cerium oxide/bismuth ferrite/reduced graphene oxide, where the cerium oxide/bismuth ferrite complex is supported on reduced graphene oxide, and the particle size of the cerium oxide/bismuth ferrite complex is less than 10 nm. USE - The complex is used as a solid propellant combustion catalyst for catalyzing the combustion of a solid propellant (claimed). ADVANTAGE - The complex: reduces the sensitivity of the propellant components; and significantly improves the decomposition efficiency of the main components of the propellant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the sub-nano cerium oxide/bismuth ferrite/reduced graphene oxide complex, comprising adding cerium nitrate, ferric nitrate and bismuth nitrate to the graphite oxide solution, adding potassium hydroxide aqueous solution, uniformly stirring and mixing, and carrying out hydrothermal reaction.
