▎ 摘  要

NOVELTY - Preparing bismuth-metal organic framework/reduced graphene oxide material, involves (a) adding bismuth salt or its hydrate into organic solvent, stirring to dissolve, adding trimesic acid, continuously stirring, transferring to reaction kettle, reacting at 100-150℃ for 10-48 hours, washing obtained product and drying to obtain bismuth-metal organic framework; and (b) dispersing bismuth-metal organic framework in graphene oxide aqueous solution, transferring to reaction kettle, reacting at 150-200℃ for 6-24 hours, and freeze-drying resulting product to obtain bismuth-metal organic framework/reduced graphene oxide material. USE - The method is useful for preparing bismuth-metal organic framework/reduced graphene oxide material used as anode material for alkali metal battery (claimed). ADVANTAGE - The method can generate alloying reaction with alkali metal ion, the alkali metal ion can be reversibly inserted in the hole of the metal framework, can be used as alkali metal host site, provides three-dimensional conductive network, exhibits good electrochemical performance, and displays a wide application prospect in the aspect of alkali metal ion battery.
