Characteristics and Applications of Graphitic Carbon Nitride Nanocomposite

Abstract

Graphitic carbon nitride (g-C<sub>3</sub>N</sub>4</sub>) has attracted much attention due to their diverse properties such as optical properties, unique structure, morphology modify, chemical stability, and inexpensive and facile synthesis. With these special properties, aromatic tri-s-triazine carbon nitrides show broad interdisciplinary potential for a variety of applications. One of the issues with g-C<sub>3</sub>N</sub>4</sub> is the recombination of photogenerated electron-hole pairs. It is difficult for single-component photocatalysts to harvest a large portion of the solar spectrum while possessing adequate space charge separation and efficient redox capability. Building g-C<sub>3</sub>N</sub>4</sub>-based doped or heterostructures can induce electron-hole pair separation through charge transfer across the interface. We systematically analyzed and discussed the recent research developments of g-C<sub>3</sub>N</sub>4</sub> nanocomposites, including the preparation of g-C<sub>3</sub>N</sub>4</sub>, characterization of microstructure, various modifications, energy-related and applications. Finally, we proposed the current challenges and promising future prospects of g-C<sub>3</sub>N</sub>4</sub>-based materials.
