This PhD project aims to develop functionalized two-dimensional (2D) membranes for selective nickel/cobalt separation. The research will focus on engineering the chemistry and structure of confined nanochannels. By introducing metal-binding functionalities (e.g., phosphonate groups), the project will investigate how differences in ion coordination preferences can be translated into selective membrane transport.
A central research question is how to balance selective ion uptake with efficient ion movement through the membrane. The project will examine how ligand identity, spatial arrangement, and channel confinement influence the binding, dehydration, and diffusion of these ions. Particular emphasis will be placed on elucidating the functionalization-interaction-property relationship in nickel/cobalt separation.
You will combine materials synthesis and membrane fabrication with advanced characterization, ion-transport measurements, and molecular modelling. The project offers interdisciplinary training at the intersection of materials chemistry, coordination chemistry, and membrane science.
Research activities will include:
- Incorporating binding groups into 2D nanochannels.
- Understanding how ion partitioning and diffusion determine selectivity.
- Evaluating separation performance and membrane stability.
We welcome applicants with backgrounds in chemistry, materials science, chemical engineering, environmental engineering, or related fields. Experience with membranes, nanomaterials, or molecular modelling would be helpful but is not essential. Curiosity and enthusiasm for experimental research are particularly valued.
