摘要：

In this study, we reported on our successful attempt to synthesize sulfur self-doped g-C3N4 by directly heating thiourea in air. The effects of treating temperature on the structural, optical and photocatalytic properties of the samples were investigated. The results demonstrated that S atoms have been incorporated into the g-C3N4 and may preferentially occupy N sites. The S-doped g-C3N4 sample prepared at 550 degrees C presented a highest photocatalytic activity in the degradation of methyl blue under visible-light irradiation. The special two-dimensional layered structure and appropriate S-doping could be responsible for the superior visible-light photocatalytic performance. (C) 2015 Elsevier B.V. All rights reserved.
