Special Issue Information

Dear Colleagues,

Membrane separation technologies have revolutionized various industrial processes due to their low cost, high efficiency, and environmental sustainability. In recent years, the emergence of two-dimensional graphene oxide material has brought about new possibilities in membrane design, offering unique atomic thickness and tuneable physical and chemical properties as an ideal membrane building block. High-performance graphene oxide membranes featuring well-defined nano/subnanometer-scale channels for controllable mass transport (for instance, gases, liquids, and ions) display tremendous potential for precise and selective molecular/ionic separation, and have been utilized in a broad spectrum of important applications related to the resources, energy, and environment fields.

The purpose of this Special Issue, “Graphene Oxide Membrane for Sustainable Energy and Environmental Applications”, is to collect recent advancements on developments and applications of innovative graphene oxide membranes. Original research articles, reviews and communications on membrane fabrications, membrane characterizations, channel constructions/regulations, transport and separation mechanisms, molecular dynamics (MD) simulations/calculations, membrane stability and scaling up technologies of graphene oxide membranes, and their utilisation and integration within sustainable energy and clean industry applications in fields including, but not limited to, gas separation, liquid separation, water purification, desalination, ions extraction and energy storage and conversation are welcome.

Graphene oxide (GO) with its atomic thickness and abundant functional groups holds great potential in molecular-scale membrane separation. However, constructing high-speed and highly selective water transport channels within GO membranes remains a key challenge. Herein, sulfonato calix[n]arenes (SCn) molecules with a cavity structure, hydrophilic entrance, and hydrophobic wall were incorporated into GO interlayer channels through a layer-by-layer assembly approach to facilitate water permeation in a water/ethanol separation process. The hydrophilic entrance enables preferential access of water molecules to the cavity over ethanol molecules, while the high hydrophobicity of the cavity wall confers low resistance for water diffusion. After incorporating SCn molecules, the membrane shows a remarkable increase in the water/ethanol separation factor from 732 to 1260, while the permeate flux also increases by about 50%. In addition, the strong electrostatic interactions between the building blocks endow the membrane with excellent swelling resistance even under a high water content. This work provides an effective strategy of constructing high-efficiency water transport channels in membrane. Full article
