摘要 石墨烯由于其独特的性能在水污染治理领域成为一种极具潜力的环境功能材料。本文综述了近几年石墨烯、氧化石墨烯及其复合材料在水污染物治理中的四方面典型应用,即作为吸附剂、光催化剂、电催化氧化剂和其它催化氧化剂(活化H2O2、过一硫酸盐)。从不同类型的水污染物角度出发,分类概述了针对重金属离子、染料类污染物、新兴环境污染物和一些无机营养元素的处理过程中石墨烯的添加对材料功能及体系作用机理的影响,还综合分析了一些重要水环境因子(如pH值,污染物浓度等)、催化剂自身的性质和石墨烯掺杂量等因素对污染物去除效率的影响。最后,针对目前石墨烯基材料在水污染治理领域的研究应用存在的问题做了总结并展望了今后研究的方向。 Graphene-based nanomaterials have attracted increasing attention in different areas,such as material science,chemical engineering and environmental science.In recent years,it and its derivatives (e.g.graphene oxide,reduced graphene oxide) have been considered promising functional materials in water pollution control because of their many unique properties.Recent intense research on the development of graphene-based composite materials has expanded their application to water treatment.Progress in the use of graphene,graphene oxide and graphene-based composite materials in water pollutant treatment is reviewed,including their use as adsorbents,photocatalysts,and the oxidant and oxidant (e.g.H2O2,peroxymonosulfate) activators in electrocatalysis.Water pollutants are heavy metal ions,dyestuffs,some inorganic nutrients and the emerging environmental pollutants.Not only are the mechanisms of the use of graphene and its derivatives in different treatment processes considered,but the effects of important factors on the removal efficiency of pollutants are analyzed,such as environmental factors (e.g.pH,pollutant concentration),the properties of the materials (e.g.particle size,surface charge) and the concentration and morphology of the material.Current problems of using graphene-based composite materials in water treatment are summarized and future research directions are proposed.
