Phosphorus-Doped Carbon Nitride Solid: Enhanced Electrical Conductivity and Photocurrent Generation

摘要

Carbon nitrides have attracted worldwide attention, because of thentheoretical prediction of their unusual properties.n1nAs there are manynways to substitute carbon with nitrogen in graphite, carbon nitridesnopen various possibilities in constructing scaffoldsn2nwith new andnexciting properties from mainly C and N. For example, graphitic-C3N4n(g-C3N4) and its incompletely condensed precursors have shownnpromising applications in the sustainable energy field as heterogeneousnmetal-free catalysts for CO2 reduction.n3nThis is because they possessna very high thermal and chemical stability and an appealing electronicnstructure with appropriate band positions and gaps suitable for a varietynof relevant chemical reactions.
