Method for producing graphite carbon nitride

Abstract

The graphitic carbon nitride method (g-C3N4) consists in mixing the melamine precursor (2,4,6-triamino-1,3,5-triazine, 99%) in an amount of 4 g to 5 g with distilled water in an amount of 8 to 9 drops, placing it in a hydraulic press, the process is carried out at a pressure of 150 MPa to 250 MPa, at a temperature of 20°C to 25°C, for 15 s to 25 s, then pressing it into a disc with dimensions of Ø25 and a thickness of 2 mm to Ø35 and a thickness of 4 mm, the disc thus obtained is placed in an aluminum oxide crucible and heated in an air atmosphere at a temperature of 450°C to 650°C, at a heating rate of 4°C / min to 6°C / min, for 1.5 h to 2.5 h, and then crushed into a homogeneous powder.
