In article number 1903572, In Young Kim, Ajayan Vinu, and co‐workers discover thermodynamically stable C3N7 composed of tetrazine, triazole and guanidine moieties. Its structure is buckled due to electrostatic repulsion between nitrogen atoms. This study proves that nitrogen atoms in the tetrazine moiety of C3N7 are very effective in the adsorption of O2 species for the oxygen reduction reaction....
Carbon nitrides with a high N/C atomic ratio (>2) are expected to offer superior basicity and unique electronic properties. However, the synthesis of these nanostructures is highly challenging since many parts of the CN frameworks in the carbon nitride should be replaced with thermodynamically less stable NN frameworks as the nitrogen content increases. Thermodynamically stable C3N7 and C3N6...
Mesoporous carbon nitrides (MCN) with C3N4 stoichiometry could find applications in fields ranging from catalysis, sensing, and adsorption–separation to biotechnology. The extension of the synthesis of MCN with different nitrogen contents and chemical structures promises access to a wider range of applications. Herein we prepare mesoporous C3N5 with a combined triazole and triazine framework via a...
