Abstract

Herein we report the synthesis of a crystalline graphitic carbon nitride, or g‐C3N4, obtained from the temperature‐induced condensation of dicyandiamide (NH2C(NH)NHCN) by using a salt melt of lithium chloride and potassium chloride as the solvent. The proposed crystal structure of this g‐C3N4 species is based on sheets of hexagonally arranged s‐heptazine (C6N7) units that are held together by covalent bonds between C and N atoms which are stacked in a graphitic, staggered fashion, as corroborated by powder X‐ray diffractometry and high‐resolution transmission electron microscopy.
