NOVELTY - Producing two-dimensional iron-doped graphene involves stirring 0.5-1 mmol sodium butyrate with hydrotalcite at 60-70 degrees C constant temperature on water bath for 5-6 hours and then aging the stirred material for 12-24 hours and separating the precipitate from liquid. The precipitate is washed with deionized water for 2-3 times and then the washed material is dried to obtain sodium butyrate-modified hydrotalcite. The 1g sodium butyrate-modified hydrotalcite is adedd with 3-5 ml 10-15 wt.% ferrocene and then the obtained material is stirred for 2-3 hours. USE - Method for producing two-dimensional iron-doped graphene (claimed). ADVANTAGE - The method enables to produce two-dimensional iron-doped graphene in simple manner, and with mild reaction conditions. DETAILED DESCRIPTION - Producing two-dimensional iron-doped graphene involves stirring 0.5-1 mmol sodium butyrate with hydrotalcite at 60-70 degrees C constant temperature on water bath for 5-6 hours and then aging the stirred material for 12-24 hours and separating the precipitate from liquid. The precipitate is washed with deionized water for 2-3 times and then the washed material is dried to obtain sodium butyrate-modified hydrotalcite. The 1g sodium butyrate-modified hydrotalcite is adedd with 3-5 ml 10-15 wt.% ferrocene and then the obtained material is stirred for 2-3 hours. The stirred material is dried at 60-80 degrees C for 15-30 hours and then the dried material is ground by 20-40 meshes sieve to obtain powder. The obtained powder is kept in a vacuum tubular furnace at 400-600 degrees C for sintering for 2-4 hours and then the suntered material is cooled to room temperature. The cooled material is added with 20-40% hydrochloric acid solution and then the obtained material is stirred and dried for 3-4 hours to separate precipitate. The dried material is heated at 2000-2500 degrees C for 3-4 hours and cooled to obtain the desired product.
