Carbon nitride is a compound made up of carbon and nitrogen atoms. It can exist in various forms, including crystalline and amorphous structures. Researchers are interested in carbon nitride for its potential applications in fields like electronics, optics, and catalysis due to its unique properties. One notable form of carbon nitride is graphitic carbon nitride, which has a layered structure similar to graphite. This material is being studied for its ability to absorb light and facilitate chemical reactions, making it a promising candidate for use in solar energy conversion and environmental remediation technologies.
