Carbon nitride dispersion
Product Overview
Graphite-phase carbon nitride (g-C3N4) is a new type of material consisting of carbon and nitrogen atoms, whose crystal structure is similar to the layered structure of two-dimensional graphite, but with higher stability and unique physical and chemical properties. Graphite-phase carbon nitride is the most stable of the carbon nitride isomers, with ultra-high strength and chemical inertness, which can make up for the shortcomings of poor thermal stability of diamond. Graphite-phase carbon nitride is a typical polymer semiconductor, in which C and N atoms in the structure are sp2 hybridised to form a highly exotic π-conjugated system, and strong covalent bonds are formed between C and N, which builds up a special conjugated system of benzene-like rings and has good stability. This graphite phase carbon nitride, with a two-dimensional lamellar structure, is prepared by pyrolytic polycondensation using nitrogen-rich compounds as precursors. This method is easy to operate, has a high yield, and the structure of the product is easy to control, making it a highly promising material with (theoretically) higher carrier separation efficiency, more reactive active sites, and stronger light trapping and redox capabilities due to its unique two-dimensional lamellar structure.
