| Recent Progresses on the Photoexcitation Processes of Polymeric Carbon Nitride-Based Materials |
|
| Abstract: Recently, the metal-free polymeric carbon nitride has drawn tremendous attention by virtue of its unique material composition and electronic structure, holding great promise in optical excitation related applications, such as photocatalysis, photoluminescence, and photoelectrochemistry. The investigation of photoexcitation processes dominated by energy band structure, charge carrier behaviors and excitonic effects in polymeric carbon nitride are of great significance in understanding mechanisms, optimizing performance and expanding application. Focusing on this topic, we review recent advances in research on the photoexcitation processes of polymeric carbon nitride-based materials, by beginning with a brief introduction of the characterization techniques in these works. We then discuss the charge carrier and exciton aspects in the photoexcitation processes. The principles of universal modification strategies on photoexcitation processes are summarized. Also, the applications of the photoexcitation processes in this polymeric semiconductor are highlighted. |
