Carbon nitride has the advantages o

Carbon nitride has the advantages of high hardness, low density, high nitrogen content, good chemical stability and friction resistance. It can be used as a high-performance friction resistant material and a nitrogen source for synthesizing metal nitrides. Because of its unique optical and electronic properties, it has broad application prospects in materials, electronics, optics and other fields, such as sensors, metal corrosion protection, energy storage materials, etc.; carbon nitride As an organic semiconductor non-metallic photocatalyst, it has the advantages of environmental protection, simplicity and low cost in the fields of photocatalytic decomposition of water and degradation of organic pollutants, which is of great significance in solving energy development and environmental governance.
