摘要：本试验通过一步热解制备碳自掺杂氮化碳（CCN），证实其桥接氮原子被碳原子取代，并研究可见光照射下催化剂活化过二硫酸盐（PDS）降解双酚A的性能。结果表明，由于离域大π键的形成，光激发电荷在分离和转移方面得到极大的改善，因此CCN降解双酚A的性能得到极大提高。

Abstract： In this experiment， carbon self-doped carbon nitride （CCN） is prepared through one-step pyrolysis， confirming that its bridging nitrogen atoms are replaced by carbon atoms， and the degradation performance of bisphenol A by catalyst activated peroxydisulfate （PDS） under visible light irradiation is studied. The results indicate that due to the formation of delocalized large π bonds， the separation and transfer of photoexcited charges have been greatly improved， resulting in a significant improvement in the performance of CCN in degrading bisphenol A.
