Metal-free n/n-junctioned graphitic carbon nitride (g-CN): a study to elucidate its charge transfer mechanism and application for environmental remediation.

Graphitic carbon nitride (g-CN) has been regarded as a promising visible light-driven photocatalyst ascribable to its tailorable structures, thermal stability and chemical inertness. Enhanced photocatalytic activity is achievable by the construction of homojunction nanocomposites to reduce the undesired recombination of photogenerated charge carriers. In the present work, a novel g-CN/g-CN metal-free homojunction photocatalyst was synthesized via hydrothermal polymerization.
