NOVELTY - Dried sodium butyrate-modified hydrotalcite is added to diethyl-methoxy-borane tetrahydrofuran solution, stirred, vacuum-dried, and ground to obtain powder having size of 20-40 mesh. Resultant powder is heated in vacuum furnace, calcined, and cooled to room temperature. Calcined powder is added to hydrochloric acid solution, stirred under nitrogen atmosphere, precipitated and dried. The obtained product is heated under vacuum for 3-6 hours, and cooled to obtain two-dimensional boron-doped heteroaryl graphene. USE - Preparation of two-dimensional boron-doped heteroaryl graphene (claimed). ADVANTAGE - The method efficiently provides two-dimensional boron-doped heteroaryl graphene, by simple method under mild reaction condition. DETAILED DESCRIPTION - 20-50 Mesh talc is added to 0.5-1 mmol 0.1-1 %mass aqueous solution of sodium butyrate, stirred at 60-70 degrees C in water bath for 5-6 hours, aged for 12-24 hours, and precipitate is then separated from the liquid. The resultant precipitate is washed using deionized water and dried to obtain sodium butyrate-modified hydrotalcite. 1 g Dried sodium butyrate-modified hydrotalcite is added to 2-3 ml 10-15 %mass diethyl-methoxy-borane tetrahydrofuran solution, stirred for 2-3 hours under nitrogen atmosphere, vacuum-dried at 60-80 degrees C for 15-30 hours, and ground to obtain powder having size of 20-40 mesh. The resultant powder is placed in vacuum furnace, heated at 400-600 degrees C, calcined for 2-4 hours, and cooled to room temperature. The calcined powder is added to 5-10 ml 20-40 %mass hydrochloric acid solution, stirred for 3-4 hours under nitrogen atmosphere, precipitated and dried. The obtained product is heated at 2000-2500 degrees C under vacuum for 3-6 hours, and cooled to obtain two-dimensional boron-doped heteroaryl graphene.
