We report a highly versatile and one-pot microwave route to the mass production of three-dimensional graphene-carbon nanotube-iron oxide nanostructures for the efficient removal of arsenic from contaminated water. The unique three-dimensional nanostructure shows that carbon nanotubes are vertically standing on graphene sheets and iron oxide nanoparticles are decorated on both the graphene and the carbon nanotubes. The material with iron oxide nanoparticles shows excellent absorption for arsenic removal from contaminated water, due to its high surface-to-volume ratio and open pore network of the graphene-carbon nanotube-iron oxide three-dimensional nanostructures.
我们报告了一种高度通用且一锅微波路线，用于大规模生产三维石墨烯-碳纳米管-氧化铁纳米结构，以有效去除受污染水中的砷。独特的三维纳米结构表明，碳纳米管垂直站立在石墨烯片上，氧化铁纳米颗粒装饰在石墨烯和碳纳米管上。具有氧化铁纳米颗粒的材料表现出优异的吸收能力，可从受污染的水中去除砷，这归因于其高的比表面积和石墨烯-碳纳米管-氧化铁三维纳米结构的开放孔网络。
