1. a nanometer γ

  • -MnO 2the preparation method of/graphene aerogel composite material, is characterized in that;

    comprise the following steps;

    (1) the Hummers legal system passing through to improve is for graphite oxide;

    (2) described graphite oxide is by after ultrasonic disperse is in water, be placed in closed container, be carry out clearing up reduction 3 ~ 15min under the microwave of 500W ~ 900W at power, obtain Graphene hydrogel, described Graphene hydrogel, through freeze drying, obtains graphene aerogel;

    (3) by described graphene aerogel by after ultrasonic disperse is in water, add manganous salt and stir, then add persulfate carry out oxidation reaction at 50 DEG C ~ 90 DEG C temperature, oxidation reaction product, through washing, dry, obtains nanometer γ

    -MnO 2/ graphene aerogel composite material.
