# Influence of Inner Lining Atoms of Multilayered Hexagonal Boron Nitride Porous Membrane on Desalination

## TL;DR

This study explores how different inner lining atoms in hexagonal boron nitride nanopores affect water desalination performance.

## Contribution

The novelty lies in comparing B-edged, N-edged, and BN-edged nanopores in h-BN for water conduction.

## Key findings

- B-edged nanopores showed higher water permeability compared to N-edged and BN-edged nanopores.
- The water conduction of h-BN nanopores was found to be comparable to that of graphene nanopores.
- The inner lining atoms significantly influence the desalination efficiency of the membrane.

## Abstract

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.
