利用分子动力学模拟方法,发现不同孔径的钻孔石墨烯对氢气和氮气有很好的分离性.当挖去了10个碳原子,孔径为0.3725 nm时,分离效率可以达到100%.由结果可以预见,钻孔石墨烯将会在气体分离和纯化方面有应用潜力.
Using molecular dynamics simulation, it was found that graphene with different pore sizes has good hydrogen and nitrogen separability, and the separation efficiency can reach 100% when 10 carbon atoms are excavated and the pore size is 0.3725 nm. It is expected that drilling graphene will have potential applications in gas separation and purification.
