The presence of specific bonds inside the carbon lattice makes BCNs structure to differ from boron and nitrogen co-doped with graphene. However, the most common methods for the fabrication of BCN, replaces graphene with boron and nitrogen atoms, which adjusts the bandgap of the material as observed in hexagonal (h-BCN) or cubic (c-BCN) crystal structures . Studies have reported that, based on the ratios of boron, carbon, and nitrogen, different distribution of graphene, boron and nitride could be observed in the with the formation of complex interfacial BxCyNz layers.
