Recent findings have demonstrated that the desalination and purification of contaminated water and the separation of ions and gases, besides solutions to other related issues, may all be achieved with the use of membranes based on artificial nanoporous materials. Before the expensive stages of production and experimental testing, the optimum size and form of membrane nanopores could be determined using computer-aided modeling. The notion that rectangular nanopores created in a multilayered hexagonal boron nitride (h-BN) membrane in a way that results in different inner lining atoms would exhibit unique properties in terms of the water penetration rate is put forth and examined in the current study. Nanopores in boron nitride sheets can be generated with the inner lining of boron atoms (B-edged), nitrogen atoms (N-edged), or both boron and nitrogen atoms (BN-edged). In this study, we compared the three different inner-lined nanopores of boron nitride nanosheets to a comparable-sized graphene nanopore and evaluated the water conduction.
最近的研究结果表明，除了解决其他相关问题外，利用基于人工纳米多孔材料的膜可以实现对受污染水的脱盐和净化以及离子和气体的分离。在进行昂贵的生产和实验测试阶段之前，可以使用计算机辅助建模来确定膜纳米孔的最佳尺寸和形状。本研究提出并检验了这样一种观点：在多层六方氮化硼（h-BN）膜中以导致不同内衬原子的方式产生的矩形纳米孔在水渗透速率方面将表现出独特的性质。氮化硼片中的纳米孔可以通过硼原子内衬（B边）、氮原子内衬（N边）或硼和氮原子内衬（BN边）来生成。在本研究中，我们将氮化硼纳米片的三种不同内衬纳米孔与尺寸相当的石墨烯纳米孔进行了比较，并评估了水传导情况。
