摘要:
为了减弱石墨烯纳米片的聚集并得到高性能的石墨烯基复合材料,先利用微波将氧化石墨烯还原为石墨烯,再与氢氧化铜进行复合得到氢氧化铜/石墨烯复合材料. 用X射线衍射和扫描电子显微镜表征了复合材料的结构与微观形貌. 结果表明氢氧化铜纳米颗粒均匀地分布在石墨烯表面,有效减弱了石墨烯纳米片的堆积聚集. 并对氢氧化铜/石墨烯复合材料进行了染料吸附测试,复合材料对于甲基橙的去除率达到了91.77%. 与单独的氢氧化铜相比,复合材料中石墨烯与氢氧化铜之间的相互作用使得复合材料具有高的吸附能力;与单独的石墨烯相比,复合材料中高密度的氢氧化铜使得复合材料容易从废水体系中分离回收,再次利用. 这些特征使得氢氧化铜/石墨烯复合材料能被有效用于废水处理领域.
Abstract:
To reduce the aggregation of graphene nanosheets and obtain graphene-based composites with high performance, the composites of graphene and copper hydroxide were successfully prepared via the microwave-assisted reduction of graphene oxide and the subsequent chemical deposition of copper hydroxide on the graphene nanosheets. Scanning electron microscope and X-ray diffraction were carried out to characterize the copper hydroxide/graphene composite. The results indicate that the aggregation of graphene nanosheets is reduced due to the uniform distribution of the copper hydroxide/graphene nanoparticles on the graphene nanosheets. Moreover, the corresponding adsorption performance of methyl orange from waste water is also investigated. For the copper hydroxide/graphene composite, the removal efficiency is 91.77%. Compared with copper hydroxide, significantly improved adsorption activity of the composite is obtained due to the interaction between graphene nanosheets and the copper hydroxide/graphene. Compared with graphene, the composite can be easily separated from solution after adsorption. After simply washing with ethanol, the composite can be reused without any obvious loss of adsorption capability. These features make the copper hydroxide/graphene composite an excellent candidate in the field of waste water treatment.
