| 中文摘要: |
| 聚合氮化碳(PCN)具有稳定、抗腐蚀、特殊表面电子结构及可见光响应等特点。PCN基Z型光催化体系不仅具有较高的光生载流子分离效率,且氧化还原能力高,在光催化领域具有巨大的应用前景。本文总结了3种Z型光催化体系,并分别阐述了作用机理。此外,我们介绍了一些PCN基光催化剂的合成方法,综述了此类催化剂在光催化分解水和CO2光还原领域的应用。最后,我们展望了PCN基光催化体系目前存在的问题及研究方向。 |
| 英文摘要: |
| Polymeric carbon nitride (PCN) has impressive properties including its stability,anti-corrosion,unique surface electronic structure,and visible-light response capability.Particularly,PCN-based Z-scheme systems are potential catalysts in photocatalytic fields due to their more effective separation of photo-generated carriers as well as superior redox ability.This review mainly introduces three types of Z-scheme photocatalysts with clarifying the corresponding mechanism pathways during photocatalytic reactions.In addition,we summarize the common synthesis approaches on PCN-based Z-scheme photocatalysts followed by the photocatalytic applications on water splitting and CO2 reduction.Finally,this review points out some existing challenges and the future study directions in related fields. |
