NOVELTY - A dried method for manufacturing a graphene oxide is disclosed. The dried method comprises: a carbon material providing step providing a carbon material and an annealing step. In the annealing step, the carbon material is heated to a target temperature with a heating rate under a micro-oxygen environment and maintaining the target temperature for a holding time to obtain a graphene oxide, wherein the oxygen amount of the micro-oxygen environment is 1-1000 ppm, wherein the heating rate is 1-10 DEG C /minute, wherein the target temperature is 500-1500 DEG C, wherein the holding time is 1-100 hours.
