preparation example Construction

[0019] The preparation method of described ferric oxide-graphene nanocomposite comprises the following steps:

[0020] Step 1, natural graphite powder obtains graphene through oxidation-reduction reaction;

[0021] Mix natural graphite powder and hydrogen peroxide evenly, then slowly add concentrated sulfuric acid dropwise, stir and react at 40°C for 5 hours, cool to room temperature after the reaction, and obtain a graphene oxide solution; wash the graphene oxide solution with dilute hydrochloric acid, and then use ultra-pure Wash with water until neutral; slowly add sodium borohydride solution dropwise to the washed graphene oxide solution, stir and react at 10°C for 3 hours to obtain a graphene solution, and then wash with ultrapure water 5-10 times for use; wherein , the mass-volume ratio of natural graphite powder, hydrogen peroxide, concentrated sulfuric acid and sodium borohydride with a concentration of 6mol / L is 3g: 50ml: 10ml: 14ml.

[0022] Step 2, preparing ferric...
