| Abstract Scope |
Metal-organic frameworks (MOFs) are like tiny sponges with well-defined pores, making them ideal for precise and fast separation processes. However, creating ultrathin MOF membranes that can withstand water has been a major hurdle. This research introduces a breakthrough in overcoming this challenge. We successfully synthesized ultrathin (2D) nanosheets. These nanosheets were then used as building blocks to assemble ultrathin membranes that are remarkably stable in water. The fabricated membrane exhibited remarkable performance in solute and ion separation. Notably, it achieved a very high rejection rate towards organic dyes, even for molecules with a relatively low molecular weight of 300 mg/mol. Additionally, the membrane demonstrated an impressive water permeance of 40 L/(mē·h·bar), signifying its efficient transport properties. Furthermore, the MOF membrane maintained its separation efficiency for over two days of continuous operation without any measurable performance decay. it is a promising candidate for various applications demanding functionality under harsh conditions. |
