摘要：

Exfoliating g-C3N4 into 2D nanosheet to minimize the stacking layer for the improvement of charge transfer and separation is considered to be the effective measure to enhance its photocatalytic performance. However, no matter what method is used, the exfoliated g-C3N4 nanosheet shows decreased optical absorption compared to the pristine bulk-like one. In this work, a simple one-step sulfur doping method is proposed on the basis of exfoliated g-C3N4 nanosheet, which can directly regulate the band structure of g-C3N4 and enhance its optical absor...
