功能化石墨烯对亚甲基蓝染料吸附的密度泛函理论研究
The adsorption study of functionalized graphenes on methylene blue dyes:density functional theory method
摘要
Abstract
Dyes in water have been widely discovered,and dye pollution is one of the important factors for the water pollution,due to the wide application of dyes in food,printing,textile and other industries.Therefore,pretreatment of dyes in water has become extremely important.The adsorption properties of pure and functional-ized graphene can be applied to the detection and removal of dyes in water.In this study,the adsorption mecha-nism of pure graphene and functionalized graphene on methylene blue(MB)was investigated by density func-tional theory method.The results showed that pure graphene and functionalized graphene have a certain degree of adsorption of MB,among which the adsorption of functionalized graphenes on MB is stronger than that of pure graphene on MB.There is the strongest adsorption of graphene functionalized with epoxy,carboxyl and hydroxyl three groups.The results are hopeful to provide meaningful theoretical guidance for graphene materials in the ad-sorption application of organic dyes.关键词
