1. a kind of nanometer of γ

  • -MnO2The preparation method of/graphene aerogel composite material, it is characterised in that:

    Include the following steps:

    (1) graphite oxide is prepared by improved Hummers method;

    (2) it after the graphite oxide passes through ultrasonic disperse in water, is placed in closed container, is the micro- of 600W~700W in powerResolution 5~10min of reduction is carried out under wave, obtains graphene hydrogel, the graphene hydrogel is by freeze-drying to get stoneBlack alkene aeroge;

    (3) after the graphene aerogel being passed through ultrasonic disperse in water, manganous salt is added and stirs evenly, adds over cureHydrochlorate carries out 6~10h of oxidation reaction at a temperature of 50 DEG C~90 DEG C, and oxidation reaction product is washed, dry, obtains a nanometer γ

    -MnO2/ graphene aerogel composite material;

    The mass ratio of the graphene aerogel, manganous salt and persulfate is 50;

    10~100:

    15~200.
