found: Wikipedia, June 30, 2020(Graphitic carbon nitride (g-C₃N₄) is a family of carbon nitride compounds with a general formula near to C₃N₄ (albeit typically with non-zero amounts of hydrogen) and two major substructures based on heptazine and poly(triazine imide) units which, depending on reaction conditions, exhibit different degrees of condensation, properties and reactivities)
found: Physical chemistry chemical physics, v. 19 (2017):p. 15613 (Carbon nitride compounds with high N : C ratios and graphitic to polymeric structures) p. 15614 (Wikipedia entry for "graphitic carbon nitride"' states: "Graphitic carbon nitride (g-C₃N₄) is a family of compounds with a general formula near to C₃N₄ and structures based on heptazine units which, depending on reaction conditions, exhibit different degrees of condensation,properties and reactivities". That definition is misleading for a number of reasons. First, most of the materials prepared to date contain not only C and N, but also substantial quantities of H as an essential component of their structures, and these carbon nitride forms are in fact best described as C[subscript]xN[subscript]yH[subscript]z compounds)
found: Graphitic carbon nitride - an overview, via ScienceDirect, June 30, 2020(g-C3N4 is a polymeric material composed of tris-triazine-based patterns with the C/N ratio=3/4 and small amount of H. Since it exhibits a stacked structure, g-C3N4 is often considered as sp2-hybridized nitrogen-substituted graphene; Graphitic carbon nitride (g-C₃N₄) is a relatively new type of carbon-based material that has been synthesized only in the last few years; Graphitic carbon nitrides (g-C₃N₄) are another promising material for photocatalytic applications as metal-free environmentally benign catalysts. Graphitic carbon nitride is a graphite analog and the stable allotrope of carbon nitride at ambient conditions)

Graphitic carbon nitride (g-C₃N₄) is not only the most stable allotrope of carbon nitrides at ambient atmosphere, but it also has rich surface properties that are attractive for many applications, including catalysis, due to the presence of basic surface sites)
