Utilizing non-equilibrium molecular dynamics simulations, we examined the ion separation facilitated by an electric field through a borophene sheet with pores. This research was inspired by the potential use of such a system in membrane-driven desalination of sea and ocean waters. Our findings indicate a marked improvement in separating both negative and positive ions from water, contingent upon electric field strength and the radius of the membrane pore. Notably, beyond a specific pore radius, this enhancement reaches a saturation point. The results highlight the potential of a high-efficiency system for producing fresh water from saline sources, emphasizing the synergistic effect of membrane porosity and the strength of the applied electric field.
