Carbon nitride Oxide (g-C3N4)O and heteroatomic N-graphene (azagraphene) as perspective new materials in CBRN defense

Abstract

In the twenty first century, there was an abrupt growth in the number of terrorist attacks and local military conflicts. Weapons of mass destruction, in particular, chemical weapons, are now being used again in the Syrian conflict. Therefore, the development of modern means of protection against weapons of mass destruction is becoming extremely relevant. The most important modern tool for the timely detection of substances that are deadly dangerous to humans in CBRN defense is a new generation of sensors – nanosensors based on nanomaterials. As a promising material for the creation of a new generation of nanosensors, graphite-like carbon nitride and its nanostructured and doped derivatives attract special attention. The water-soluble carbon nitride oxide (g-C3N4)O was synthesized by the gas phase method under special reaction conditions of pyrolysis of melamine and urea. Reduction by the hydroquinone of carbon nitride oxide (g-C3N4)O yields nanostructured reduced carbon nitride (or reduced multilayer azagraphene).
