Graphitic Carbon Nitride Based Composites as Advanced Photocatalysts from Synthesis to Application: A Review

Charles K Bandoh, Eric S Agorku, Francis K Ampong

In the search for an effective semiconductor for photocatalytic applications, certain important necessities such as narrow bandgap for efficient absorption of visible light, suitable band location for an effective redox reaction, low recombination rate, etc. need to be kept in mind. It is apparently clear that a no single semiconductor can satisfy these requirements. Graphitic Carbon Nitride (g-C3N4)-based semiconductor nanocomposites have however been found to possess these all-important qualities. This study outlines the most recent developments in the design and fabrication of g-C3N4-based materials, as well as their applications in photo catalysis.
