Construction of SnO2/graphene-like g-C3N4 with enhanced visible light photocatalytic activity. Issue 57 (20th July 2017) - Ji, Haiyan
Abstract : 2D/2D SnO2 /GL-C3 N4 photocatalysts with large specific surface area and high coupling heterointerface extent were synthesized by an environmental friendly hydrothermal method, showing excellent photocatalytic performance on RhB degradation. Abstract : In this work, SnO2 /graphene-like g-C3 N4 (SnO2 /GL-C3 N4 ) 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-C3 N4 (GL-C3 N4 ). The 25 wt% SnO2 /GL-C3 N4 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-C3 N4, respectively. In addition, the possible photocatalytic mechanism of rhodamine B (RhB) degradation by SnO2 /GL-C3 N4 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-C3 N4 -based photocatalysts with high and stable performance for pollutant degradation.
