NOVELTY - Preparing graphene-graphene nano ribbon sponge comprises (1) determining concentration of graphene oxide (GO) and graphene oxide nano ribbon (GONR) solutions by gravity method, in mg/ml, (2) according to the mass ratio of GO to GONR is 1:1, extracting corresponding volume of solution into the mold, stirring and mixing, (3) mixing GO-GONR solution in the cold well of the freeze dryer for about 24 hours, and evacuating to start freeze-drying to ensure that the sample is completely dry, the freeze-drying time needs at least 48 hours, (4) taking out the freeze-dried sample at this time, it is the GO-GONR ribbon that has not been reducing, i.e., graphene oxide-graphene oxide nano ribbon composite sponge, (5) reducing in 90 degrees C hydrazine hydrate for 24 hours, cooling, taking out, placing into a vacuum drying box at 100 degrees C for 24 hours for removing residual hydrazine hydrate, and cooling to room temperature to obtain graphene-graphene nano ribbon sponge. USE - The method is useful for preparing graphene-graphene nano ribbon sponge. ADVANTAGE - The method: has simple operation.
