Method for the synthesis of water-soluble oxide of graphite-like carbon nitride

Synthesis of reduced carbon nitride at the reduction by hydroquinone of water-soluble carbon nitride oxide (g-C3N4)O

“…Carbon nitride oxide as a new substance was received for the first time by us under the special reactionary conditions of pyrolysis process [5]. The main feature of a method for the synthesis of carbon nitride oxide is that it as well as the intermediate products of pyrolysis, in particular, melamine and urea, is formed in an vapor-gas reactionary space and mainly is located by means of the deposition and the condensation in more lowly temperature (concerning the most highly temperature reaction zone) zones of reactionary space, far from a place of precursor localization.…”

“…In support of the preferable formation of carbon nitride oxide the pyrolysis of melamine was carried out in the presence of the microamount of oxygen according to reactionary conditions described in details by us earlier [5]. As the molecule of urea contains oxygen (СO 2 N 2 H 4 ), thus, to obtain carbon nitride oxide as partially oxidized carbon nitride the additional oxygen as a reagent is not required.…”

“…At the presence of oxygen it can easily oxidize with the formation of the partially oxidized derivatives of carbon nitride. In actuality, we established [5] that carbon nitride oxide (g-C 3 N 4 )O (16.1 mass%) and oxygen-doped carbon nitride O-g-C 3 N 4 (8.1 mass%) are formed simultaneously at the thermal conversion of melamine molecules.…”

“…However, the main purpose for the experts on heterocarbon is to synthesize a heteroatomic (carbon-nitrogen) graphene (azagraphene [5]). The developed route for the obtaining of graphene from graphite (graphite -graphite oxide (graphene oxide) -graphene) is extremely attractive.…”

“…The asymmetry of an electronic density distribution in different forms of heterocarbon (azafullerene, borafullerene, azaborafullerene, C-N-nanotubes, and N-doped graphene) gives the base to consider it as the most perspective materials for the wide range of applications. Carbon nitride (g-C 3 N 4 ) can be considered as hetero-carbon which most saturated with nitrogen [5]. Graphite-like carbon nitride is a lowcost, robust, metal-free, and visible-light-active photocatalyst in the field of solar energy conversion [6].…”
