Abstract:
Nanodisperse crystalline carbon nitride (C$_3$N$_4$) can be obtained by the method of dynamic synthesis in a hypersonic jet of electric-discharge carbon plasma in nitrogen atmosphere. The data of high-resolution transmission electron microscopy show that the crystalline structure of the synthesized material is close to a theoretical structural model of the $\alpha$ phase of C$_3$N$_4$. Flattened C$_3$N$_4$ nanocrystals possess a unique structure and appear as quasi-two-dimensional multilayer particles without any known analogs.
