Graphite type carbon nitride (g-C3N4 ) polymer is a novel semiconductor non - metallic photocatalyst. Nitrogen- rich and low-cost materials such as melamine, urea and dicyandiamide can be used as precursors. With good chemical stability and thermal stability at the same time, it can not only absorb sunlight into chemical energy, and can completely environment pollutants, and widely used light catalysis, such as light degradation of organic pollutants, photolysis aquatic ammonia selective optical oxygen and organic synthesis, in terms of energy shortage and environmental protection has the very...
