摘要
石墨烯是一种由碳原子以sp^2杂化轨道形成的只有一个碳原子厚度的二维碳质新材料,优异的特性使其在很多领域有着广泛应用。简述了石墨烯的特性,介绍了石墨烯及其氧化物的制备方法,详细阐述了石墨烯及其氧化物的复合材料在水处理领域的应用。石墨烯及其氧化物加入到其他材料中可提升其他材料的性能,但它们对水中有机物及重金属离子吸附机理还有待进一步研究。
Graphene is a kind of new material consists of carbon atoms with a sp^2 hybrid orbital and the carbonatoms are 2-dimentional having only one carbon atom thickness. It has been widely used in many fields because ofits excellent characteristics. The characteristics of graphene are described,and the preparation methods forgraphene and its oxide are introduced. The application of graphene and its oxide composite materials to watertreatment fields are expounded in detail. Adding graphene and its oxide can improve the performances of othermaterials,but further research on its adsorption mechanisms for organic substances and heavy metal ions in water isstill needed.
