▎ 摘  要

NOVELTY - The preparation method of graphene oxide-wrapped bismuth-tungsten-oxide microspheres-nano composite material involves mixing bismuth-tungsten-oxide nanoparticle suspension having a pH of 3-5, and graphene oxide solution, precipitating to obtain a precipitate of graphene oxide-wrapped bismuth-tungsten-oxide microspheres-nano composite material. USE - Preparation method of graphene oxide (GO)-wrapped bismuth-tungsten-oxide microspheres-nano composite material used as energetic material with research department explosive (RDX) thermal decomposition catalyst and high melting explosive (HMX) thermal decomposition catalyst (all claimed). ADVANTAGE - The method achieves steady-state combustion of solid propellant and reduces the pressure exponent. DETAILED DESCRIPTION - The preparation method of graphene oxide-wrapped bismuth-tungsten-oxide (GO-Bi2WO6) microspheres-nano composite material involves mixing bismuth-tungsten-oxide (Bi2WO6) nanoparticle suspension having a pH of 3-5, and graphene oxide solution, and precipitating to obtain a precipitate of graphene oxide-wrapped bismuth-tungsten-oxide microspheres-nano composite material. An INDEPENDENT CLAIM is included for the application of graphene oxide (GO)-wrapped bismuth-tungsten-oxide microspheres-nano composite material as energetic material containing research department explosive (RDX) thermal decomposition catalyst and high melting explosive (HMX) thermal decomposition catalyst.
