▎ 摘  要

NOVELTY - Continuously synthesizing doped graphene comprises (i) introducing the catalyst in a reactor, replacing with nitrogen and keeping the inside of the reactor at 0.1-1 Mpa, (ii) pouring nitrogen into the reactor at 1000-1300 Nm3/hour, starting a heating system of the reactor, heating and melting the catalyst, raising the temperature at 1500 degrees C not less than T less than or equal to 1600 degrees C and keeping, (iii) continuously passing 5-100 Nm3/hour carbon-containing gas and 1-50 Nm3/hour doped gas into the reactor, maintaining the reaction temperature T at 1500 degrees C not less than T less than or equal to 1600 degrees C, carrying out the reaction for 0.3-0.5 seconds to form doped graphene, blowing out the doped graphene from the reactor with the tail gas, collecting, acid washing to remove entrainment catalyst, washing and drying. USE - The method is useful for continuously synthesizing doped graphene. ADVANTAGE - The graphene: has high-quality, and excellent anode and cathode material for lithium batteries; greatly improves production efficiency; opens graphene electronic band gap by doping; and improves the current carrying capacity of electrons.
