| 摘要: 通过热解-水热两步法制备了石墨烯/石墨相氮化碳/二硫化钼（RGO/g-C3N4/MoS2）复合材料并使用多种分析表征手段对RGO/g-C3N4/MoS2的结构、形貌及光催化性能进行分析。结果表明，具有异质结构的g-C3N4/MoS2与RGO复合后，通过良好的界面接触和电荷的快速转移，增强了其光生电子-空穴的分离。经可见光照射120 min后，RGO/g-C3N4/MoS2复合材料可降解97%亚甲基蓝。此外，循环实验表明RGO/g-C3N4/MoS2复合材料具有良好的稳定性，经5次循环仍能保持93.2%的光催化活性。 |

| Abstract: The reduced graphene oxide/graphitic carbon nitride/molybdenum disulfide composites (RGO/g-C3N4/MoS2) were synthesized via the pyrolysis-hydrothermal two-step method. The structures, morphologies and photocatalytic properties of as-prepared composites were characterized by various analytical characterization methods. With the good interface contact and rapid transfer of charge, the composites could enhance the photoelectron-hole separation. The results show that the GCM composites could degradation 97% methylene blue (MB) in 120 min under the irradiation of visible-light and the highest apparent reaction rate constant (k) value was 0.028 09 min-1. Moreover, the cycle experiments show that the composites had good stability and could maintained 93.2% photocatalytic activity after 5 cycles. |
