Abstract |
It was first performed a special method of pyrolysis of melamine in order to study the possibility of coproduction of carbon nitride and its oxidized derivatives. New compound as a graphite-like carbon nitride oxide (g-C3N4)O, which is isostructural analogue of graphite oxide, and doped with oxygen ( ~ 8.1 % ), carbon nitride (O-g-C3N4) were obtained. In contrast to known methods for the preparation of samples doped with oxygen carbon nitride a new route does not provide a preliminary synthesis of g-C3N4.The synthesized carbon nitride oxide is easily stratified and dissolved in water to form a flocculent solution which may contain not only ultra-thin nanosheets from several heptazine oxidized layers, but also the individual twodimensional monolayers. These monolayers can be a precursor for making reduced heptazine monolayer
(or azagraphene). The synthesized substunces were investigated by methods chemical and X-ray analyses, IR spectroscopy, temperature-programmed desorption mass spectrometry (TPDMS) obtained products. |
