摘要

In this study,the sulfur-doped porous g-C3N4 nanosheets(CN-T-U 1.75)were synthesized successfully by one-step calcination utilizing urea and thiourea as precursors.Under visible light irradiation,CN-T-U 1.75 showed remarkable photocatalytic activity for Rhodamine B(RhB)degradation with a kinetic reaction rate constant of 0.01838 min-1.The characterization analysis indicated that CN-T-U 1.75 had a higher specific surface area and the doping altered the energy band structure.This work offers a new viewpoint on modifying the band structure of a photocatalyst using a doping strategy,as well as new insights into the generation routes of active species involved in the photocatalytic process.
