摘 要: 采用水热法成功制备了Graphene/MoS2复合材料,通过控制条件吸附降解亚甲基蓝(methylene blue,MB)溶液,研究Graphene/MoS2复合材料的光催化活性。实验结果表明,在可见光光照条件下,以MB染料模拟污染物,Graphene/MoS2复合材料相对于单一二硫化钼(MoS2)材料有更好的光催化降解效果,光照180 min光催化降解率可达76.6%,远高于MoS2材料的38.6%. 研究表明,Graphene/MoS2复合材料在降解污染物方面表现出更加优越的光催化性能。
关 键 词: 光学;Graphene/MoS2;可见光波段;光催化降解

Abstract: Graphene/MoS2 composites were successfully prepared by hydrothermal method. The photocatalytic activity of Graphene/MoS2 composite was studied by controlling methylene blue (MB) degradation. The experimental results show that, compared with the single MoS2 material, Graphene/ MoS2 composites exhibit better photocatalytic degradation efficiency under the visible-light condition and MB dye simulated pollutants. The photocatalytic degradation rate is up to 76.6% after 180 min of visible-light, which is far higher than MoS2 material (38.6%). The results show that Graphene/MoS2 composites exhibit superior photocatalytic performance in the degradation of pollutants.
