Outline of Final Research Achievements

Reverse osmosis (RO) membranes consisted of two-dimensional materials, such as graphene and graphene oxide (GO), have attracted increased attention in seawater desalination. In this research, various hybrid membranes consisted of GO and carbon nitride (CN; which is known as a photocatalyst with 2D nanosheet) have been prepared and their water permeability from saline water have been also investigated. The GO-CN hybrid membranes by electrostatic interaction were thinner and more stable in saline water than other GO and GO-CN hybrid membranes, and the lowest ion permeation were achieved. These results might be due to low void space between GO layers and CN layers for nanosheet structures and intermolecular interaction by the ionization.
