“…24,59 The C 3 N 4 stoichiometry was determined by Rutherford back scattering (RBS), while electron energy loss (EELS) measurements carried out using transmission electron microscopy (TEM) confirmed the presence of sp 2 -bonded C and N atoms. IR data showed the absence of N-H groups.…”

“…This structure was first proposed in the mid-1990's as "graphitic carbon nitride" ("g-C 3 N 4 ") by analogy with the structurally related graphite 15,16 . A nanocrystalline material with C 3 N 4 stoichiometry had been reported from chemical vapor deposition 17,18 and related models were studied theoretically 16,19,20 . Triazine-based carbon nitrides can also be exfoliated to produce layered materials analogous to few-layered graphene 21,22 .…”

We used ab initio random structure searching (AIRSS) to investigate polymorphism in C3N4 carbon nitride as a function of pressure. Our calculations reveal new framework structures, including a particularly stable chiral polymorph of space group P 43212 containing mixed sp 2 and sp 3 -bonding, that we have produced experimentally and recovered to ambient conditions. As pressure is increased a sequence of structures with fully sp 3 -bonded C atoms and three-fold coordinated N atoms is predicted, culminating in a dense P nma phase above 250 GPa. Beyond 650 GPa we find that C3N4 becomes unstable to decomposition into diamond and pyrite-structured CN2.

“…Other avenues of research have investigated the formation of layered graphitic (C,N) materials that could provide potential precursors to new high-density sp 3 -bonded phases as well as having useful properties in their own right. These compounds are now being studied extensively both experimentally and theoretically [4,[8][9][10][11][12][13][14][15][16][17][18][19][20].…”
