Photocatalytic Systems Based on Crystalline Carbon Nitride for Hydrogen Production
The current state of research on photocatalytic systems based on crystalline graphitic carbon nitride (CCN) for H2 evolution from aqueous solutions of electron-donating substrates is considered. Methods of CCN synthesis and photocatalytic properties of different samples of CCN-undoped with a controlled defect structure and doped with metals and non-metals are discussed. Possible directions for further research of such CCN-based photocatalytic systems are outlined.
