▎ 摘  要

NOVELTY - A graphene oxide interlayer loaded nanocobaltosic oxide catalyst comprises graphene oxide and cobaltosic oxide. The cobaltosic oxide is loaded on graphene oxide nanosheet (5-95 mass%). USE - A graphene oxide interlayer loaded nanocobaltosic oxide catalyst. ADVANTAGE - The catalyst has controllable grain size of nanocobaltosic oxide. Its method of preparation is simple, has moderate reaction conditions, and has short preparation time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene oxide interlayer loaded nanocobaltosic oxide catalyst, comprising: (A) adding graphene oxide into hexanol, and conducting ultrasonic dispersion for 0.5-5 hours; (B) dissolving divalent cobalt salt in hexanol; (C) slowly adding the solution prepared in (B) into the solution prepared in (C) while stirring, adding alkali solution, stirring for 2-5 hours, and obtaining mixed solution; and (D) heating the mixed solution to react at 50-150 degrees C for 5-20 hours while stirring, cooling to room temperature, washing, obtaining precipitate, vacuum drying the precipitate at 40-60 degrees C for 12-24 hours, and obtaining the catalyst.
