石墨烯及其复合材料吸附降解有机污染物的研究进展

Research Progress on Adsorption and Degration of Organic Pollutant with Graphene and Its Composite Materials

石墨烯是目前发现的唯一存在于室温条件下的二维自由态原子晶体,具有优异的电学、光学及机械性能,同时还具有良好的热学、化学稳定性,比表面积大,因而可以广泛应用于环境污染治理。有机染料类、苯系物类及农药、抗生素类等有机污染物是造成环境污染和对人体健康产生有害影响的重要污染源之一。主要综述了近几年石墨烯及其复合材料在有机染料类、苯系物类及农药、抗生素类等有机污染物中的吸附、降解、去除等应用研究。

Graphene is a two-dimensional free state atomic crystal which was only present in the room temperature conditions up to now.It not only has very good electrical,optical and mechanical properties,but also exhibits good thermal stability,chemical stability and high surface area.Therefore,graphene and its composite materials can be widely used to control environmental pollution.Organic pollutants such as organic dye,benzene series,pesticides and antibiotics are the main environmental pollutant sources which pollute the environment and threaten human health.This paper describes the application of graphene and its composites in adsorption and degration for organic contaminants in recent years.
