The invention relates to a preparation method of nitrogen-doped graphene. The preparation method comprises the following steps: adding raw materials of citric acid and melamine into methanol, stirring, performing ultrasonic treatment and drying to obtain a precursor, and calcining the precursor in a tubular furnace by two stages to finally obtain the nitrogen-doped grapheme. Compared with the prior art, the preparation method has the following advantages: the raw materials are wide in source; the steps are simple; requirements on equipment are low; in the preparation process, a reducing agent is not required, so that environment pollution is low; the prepared nitrogen-doped graphene is thin in sheet, large in specific surface area, uniform in structure and good in reproducibility.
