Synthesis of graphitic carbon nitride by reaction of melamine and uric acid

Surface modification of graphene and graphite by nitrogen plasma: Determination of chemical state alterations and assignments by quantitative X-ray photoelectron spectroscopy

“…Recently, graphitic carbon nitride (g-C 3 N 4 ) has been successfully synthesized, and its structure was described as being composed of heptazine (tri-s-triazine) blocks [49][50][51][52]. In accordance with this finding, our interpretation of the high top-surface N-content includes the formation of similar triazine clusters within the graphene plane, in addition to the pyridine, pyrrole, diazine and possible pyridazine rings at the edges of the graphene blocks [6].…”

Efficient helium separation of graphitic carbon nitride membrane

“…The framework of g-C 3 N 4 consisting of tri-s-triazine (heptazine) rings was demonstrated to be the most stable allotrope among various 2D carbon nitrides under ambient conditions [52]. More importantly, the multi-layer g-C 3 N 4 material has already been successfully synthesized by a variety of methods [53][54][55], which have paved the way for producing single-layer free-standing g-C 3 N 4 membrane, in the light of producing graphene from graphite [56]. Moreover, the excellent thermal, mechanical and chemical stabilities of g-C 3 N 4 [57] are quite promising for gas purification under arbitrary conditions.…”

Supramolecular intermediates in the synthesis of polymeric carbon nitride from melamine cyanurate

“…This reaction is promoted by sulfuric acid, which acts as a catalyst [22][23][24][25]. The results of the melamine cyanurate pyrolyzed in the range between 450 and 700 1C were presented in previous reports [24][25][26], with the significant result being the formation of crumpled and globular particles of polymeric carbon nitride with thickness ranged between 5 and 25 nm.…”

“…The pathway synthesis presented by Li et al [21] was extended to heteroatoms different from halogens by Dante et al [22][23][24][25]. In the last developments, the polycondensation reaction (see Eq.…”
