Abstract

In this work, SnO2/graphene-like g-C3N4 (SnO2/GL-C3N4) composite photocatalysts with large surface areas and abundant coupling heterointerfaces were synthesized using a hydrothermal method. The as-prepared photocatalysts exhibited distinctly manifested efficient visible light activities toward organic pollutant degradation, demonstrating remarkable synergistic effects between SnO2 and graphene-like g-C3N4 (GL-C3N4). The 25 wt% SnO2/GL-C3N4 composite showed optimal photocatalytic activity under visible light irradiation, which was almost 9 and 2.5 times as high as that of SnO2 and GL-C3N4, respectively. In addition, the possible photocatalytic mechanism of rhodamine B (RhB) degradation by SnO2/GL-C3N4 under visible light was also discussed in detail. Moreover, this work would provide a facile way for the fabrication of novel two dimension/two dimension (2D/2D) GL-C3N4-based photocatalysts with high and stable performance for pollutant degradation.
