▎ 摘　　要

NOVELTY - Preparing doped graphene involves dispersing the graphene, metal salt and/or non-metal compound in the solvent, drying, preparing composite powder, heating the reaction chamber to the preset temperature under the protection atmosphere or vacuum atmosphere, performing microwave irradiation to the reaction chamber, adding the composite powder, preparing doped graphene, the preset temperature is 500-900degrees Celsius. USE - Method for preparing doped graphene used to electro-catalysis, organic catalysis, activity of photo-catalysis and enzyme catalysis. ADVANTAGE - The method is simple, the atom doping amount is high and it can realize metal atom-non-metal atom co-doping. The method provides a thermal field environment in advance, on the one hand, it can ensure that the temperature in the reaction cavity in the microwave irradiation process is relatively stable, it ensures the consistency of the reaction environment of each batch product entering the reaction chamber at different time, the product has good uniformity, no need to re-adjust the temperature of the cavity after each reaction, so as to realize continuous production, and the method provides the wave absorbing site itself, without adding other initiator, further simplifying the operation and improving the production efficiency and the thermal field can assist the microwave to provide higher excitation energy, which is good for improving the substitution efficiency of the doped atoms to the
