NOVELTY - Preparing transition metal-nitrogen co-doped two-dimensional graphene using confinement micro reactor comprises e.g. taking hydrophobic layered material of modified cationic surfactant of montmorillonite as template, filling complex solution of polybenzimidazole and transition metal into interlayer of layered template using vacuum assisted method and the molecules are regularly arranged by regulating hydrophobicity and vacuum assisting, long chain alkyl groups of cationic surfactants is used to control hydrophobicity and interlayer spacing of the layered materials, and carrying out pyrolysis. USE - Transition metal and nitrogen co-doped two-dimensional graphene is useful as catalyst in oxidation-reduction reaction, metal air batteries, fuel cell; for catalysis of oxygen precipitation in catalytic electrolyte; and used as electrode materials for supercapacitors (claimed). DETAILED DESCRIPTION - Preparing transition metal-nitrogen co-doped two-dimensional graphene using a confinement micro reactor comprises taking hydrophobic layered material of modified cationic surfactants of montmorillonite as template, completely soluble aromatic polybenzimidazole forms complex with transition metal ion, filling complex solution of polybenzimidazole and transition metal into interlayer of the layered template using vacuum assisted method and the molecules are regularly arranged by regulating hydrophobicity and vacuum assisting, long chain alkyl groups of cationic surfactants is used to control hydrophobicity and interlayer spacing of the layered materials, where amount of addition of complex and the arrangement of the complex in the layer is restricted by regulating the spacing between the interlayer in the vertical direction under inert gas protection, carrying out pyrolysis to obtain final product.
