This PhD project focuses on developing nanoporous membranes using porous organic frameworks for efficient molecule-level separations. Advanced synthesis methods will be developed to design and synthesize high-performing membranes for applications in organic solvent nanofiltration and reverse osmosis, offering greener solutions for product purification and waste treatment across various industries.

World-pressing issues such as climate change and water scarcity have driven the need for greener and more sustainable technologies. Membrane technology is an attractive alternative due to its low carbon footprint and versatility. Membranes have been extensively applied in water treatment, seawater desalination and product purifications, and they can potentially offer more efficient solutions in separation processes across various industries. Advancing membrane materials is crucial to unlocking their full potential, enabling more efficient and sustainable industrial solutions for the future.

This PhD project aims to develop nanoporous membranes using porous organic frameworks (POFs) for molecule-level separations. POFs, constructed from organic monomers with strong covalent bonds, offer high stability and tunable properties, making them ideal candidates for designing membranes with tailored separation performance. Advanced POF thin-film synthesis methods will be developed in this project. The developed membranes will be studied for small molecule separations, for processes such as organic solvent nanofiltration (OSN) and organic solvent reverse osmosis (OSRO). These processes will offer greener alternatives for small-molecule product purification, solvent recycling and organic waste treatment, with potential applications in industries like pharmaceuticals, food, petrochemicals, fine chemicals and electronics.

This is a fully funded 3.5-year PhD studentship ideal for someone with a background in Chemical Engineering, Chemistry or Materials Science, and a strong interest in materials and separations. The project will have access to state-of-the-art facilities, including both experimental and characterization tools available at the University of Southampton.

Training will include Nanoporous material synthesis, advanced material characterization, analytical techniques, membrane performance testing, and process development.
