description The invention provides a method for preparing nano-graphite oxide particles or graphite flakes and mellitic acid simultaneously. The method comprises: taking a graphic plate as an anode, and obtaining a solution of nano carbon and mellitic acid after the graphic plate is electrified in an electrolytic cell containing de-ionized water for one to fifteen days; and then depositing the nano carbon and centrifugalizing the solution to obtain the nano-graphite oxide particles or graphite flakes with different sizes and a yellow solution containing mellitic acid; and finally adopting ethanol to extract, concentrating the extracted solution, evaporating the solution to be dry at a temperature of between 50 and 80 DEG C and obtaining the mellitic acid solid. The method utilizes the method of electrochemical oxidation of a graphite electrode and obtains monodisperse graphite oxide particles or graphite flakes with different nano sizes and the mellitic acid. The preparation method has the advantages of simple technique,
