NOVELTY - The utility model claims a graphene technology field, especially claims a heat feeding device for reducing method to prepare graphene. it can improve yield of single-layer or few layer graphene and improves the uniformity and stability of the reaction. overcomes the single-layer or few layer graphene in the present technology has low content uniformity and stability of reaction is bad. The utility model embodiment claims a thermal reduction method for preparing graphene by feeding device, the feeding device comprises a feeding device, the feeding device comprises a feeding port, a blowing gas inlet and a discharge port, the feeding port for adding graphene oxide powder or graphite oxide powder, the blowing gas inlet for introducing an inert gas, the discharge port for communication with the reaction vessel. The utility model embodiment is applied in thermal reduction method to prepare graphene.
