The high-nitrogen compound 3,6-di(azido)-1,2,4,5-tetrazine (DiAT) was synthesized by a relatively simple method and used as a precursor for the preparation of carbon nanospheres and nanopolygons, and nitrogen-rich carbon nitrides.

Preparation of carbon nanoparticles and carbon nitride from high nitrogen compound

Nanoporous metal foams are prepared by ignition of high nitrogen transition metal complexes. The ammonium salts of iron(III) tris[bi(tetrazolato)-amine], cobalt(III) tris(bi(tetrazolato)amine), and high nitrogen compounds of copper and silver were prepared as loose powders, pressed into pellets and wafers, and ignited under an inert atmosphere to form nanoporous metal foam monoliths having very high surface area and very low density.

Preparation of nanoporous metal foam from high nitrogen transition metal complexes

The high-nitrogen compound of the formula was prepared. Pyrolysis of the compound yields carbon nitrides CNand CN. The carbon nitrides vary in their density, texture, and morphology.
