| Questions And Answer | Back Directory | [Preparation]
A method for preparing graphitic carbon nitride includes the following steps: using nitrogen-rich organic matter as raw material and graphite or silicon carbide as microwave absorber, mixing the nitrogen-rich organic matter and microwave absorber uniformly, and reacting in an electromagnetic field irradiated by microwaves, controlling the pressure at 5-35 kPa, the microwave irradiation power at 2-10 kW, and the heating rate at 50-500°C/min, and holding the reaction at 450-700°C for 5-30 min to obtain graphitic carbon nitride; wherein the nitrogen-rich organic matter is one of melamine, dicyandiamide, cyanamide, thiourea, and urea. |
