| Abstract: | First from urea was synthesized carbon nitride oxide (g-C3N4)O which is formed in a vapor gas reactionary space and is deposited outside of a place of precursor localization. The reaction of urea conversion was investigated in an interval of temperatures 350–450 °С, but carbon nitride oxide is detected in the products of pyrolysis only at temperatures above 430 °С. Carbon nitride oxide is dissolved in water and at a reducing it by hydroquinone is formed reduced carbon nitride oxide consisting, as we believe, from azagraphene sheets. |
