NOVELTY - Preparing cobalt oxide/reduced graphene oxide organic alcohol molecule sensitive film involves dissolving cobalt(II) acetate tetrahydrate in deionized water, adjusting the pH value of the solution to 2.0-8.0 , stirring to get a red transparent solution A, dispersing graphene oxide uniformly in absolute ethanol and perform ultrasonic treatment to obtain solution B. According to the mass ratio of graphene oxide to cobalt(II) acetate tetrahydrate is 1mg: (5.0-20.0)mg, mixing the red transparent solution A and solution B to obtain the mixed solution C. The mixed solution C is added to the microwave hydrothermal reactor. The silicon substrate is pit into the reactor. The reactor is installed into the microwave hydrothermal instrument. USE - Method for preparing cobalt oxide/reduced graphene oxide organic alcohol molecule sensitive film. ADVANTAGE - The method enables to prepare cobalt oxide/reduced graphene oxide organic alcohol molecule sensitive film in a convenient manner with high product quality. DETAILED DESCRIPTION - Preparing cobalt oxide/reduced graphene oxide organic alcohol molecule sensitive film involves dissolving cobalt(II) acetate tetrahydrate in deionized water, adjusting the pH value of the solution to 2.0-8.0 , stirring to get a red transparent solution A, dispersing graphene oxide uniformly in absolute ethanol and perform ultrasonic treatment to obtain solution B. According to the mass ratio of graphene oxide to cobalt(II) acetate tetrahydrate is 1mg: (5.0-20.0)mg, mixing the red transparent solution A and solution B to obtain the mixed solution C. The mixed solution C is added to the microwave hydrothermal reactor. The silicon substrate is pit into the reactor. The reactor is installed into the microwave hydrothermal instrument. The temperature control mode or pressure control mode are selected for the reaction. After the reaction is completed, the solution is transferred to a microwave ultrasonic ultraviolet light combined catalytic synthesizer, and microwave and ultraviolet light treatment are performed simultaneously to obtain a cobalt oxide/reduced graphene oxide organic alcohol molecule sensitive film.
