Physical and chemical characteristics and functional properties of carbon nitride materials obtained by template synthesis

The preparation, structure, and functional properties of carbon nitride such as its photocatalytic, catalytic, and adsorption activities have been examined. The template synthesis of g-C₃N₄ allows increasing its dispersion, specific surface area, and spatial ordering, leading to enhanced photocatalytic activity of such materials in the photoreduction of carbon dioxide and larger catalytic activity in the Knoevenagel condensation as well as in the oxidation of betulin (as a support for nanodispersed ruthenium) compared with the bulk analog. Increased adsorption capacity for H₂ and CO₂ is found in the case of non-stoichiometric carbon nitride.
