Preparation and Photocatalytic Properties of Ordered Mesoporous ZnS Nanorods Loading on Graphene Composite

  • 摘要: 采用微波辅助加热法制备了石墨烯负载有序介孔硫化锌纳米棒复合材料,研究了复合材料的微观形貌和物相组成,分析了氧化石墨烯含量(0~15%,质量分数)、微波加热功率(320~800 W)和时间(0~80 min)对微观形貌和光催化性能的影响,并对复合材料的形成机理以及微观形貌与光催化性能的关系进行了探讨。结果表明:复合材料由片状石墨烯和棒状硫化锌组成,有序介孔硫化锌纳米棒均匀地分布在石墨烯表面;氧化石墨烯含量的增加有利于硫化锌纳米棒的均匀分布,微波加热功率的增加和微波加热时间的延长有利于促进硫化锌纳米棒的形成;当微波加热时间为60 min,微波加热功率为640 W,氧化石墨烯质量分数为10%时,复合材料的光催化性能最佳。
    Abstract: The composite of ordered mesoporous ZnS nanorods loading on graphene was prepared by microwave-assisted heating. The microscopic morphology and phase composition of the composite were studied; the effect of graphene oxide content (0-15wt%) and microwave heating power (320-800 W) and time (0-80 min) on microscopic morphology and photocatalytic performance was analyzed; the formation mechanism of the composite, and the relation between micromorphology and photocatalytic performance were discussed. The results show that the composite consisted of flake graphene and rodlike ZnS, and ordered mesoporus ZnS nanorods distributed on the surface of graphene evenly. The increase of graphene oxide content was favorable for dispersion of ZnS nanorods. The formation of ZnS nanorods was promoted with the increase of microwave heating power and time. The photocatalytic performance of the composite was the best when the microwave heating time was 60 min, microwave heating power was 640 W, and the content of graphene oxide was 10wt%.
