Graphite-like carbon nitride inorganic compounds were synthesized from molecular 1,2,4-triazole C 2 N 3 H 3 in high pressure and temperature conditions using a DIA-type multianvil large press. It was found that the N/C content ratio of the carbon nitrides can be systematically controlled by changing the heating temperature at 5 GPa. The substitution of nitrogen for carbon in graphene layers results in the low crystallinity of the synthesized CN compounds. It should be noted that the c-axis which is equivalent of the distance between two graphene layers, decreases monotonously with increasing N/C content ratio. This is attributed to both of the smaller atomic size of nitrogen than that of carbon and Van der Waals attraction between CN graphene layers because of the different electronegativity between nitrogen and carbon.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
