Why apply? This multidisciplinary project integrates electrochemistry, metal-organic framework-based materials, and membrane chemistry to develop the next generation of high-performance membranes and unlock new possibilities for advanced molecular separation and transport. Can you design the membrane that powers the next generation of electrolysers? Electrolysis and electrocatalysis play a key role in creating a more sustainable chemical industry. At the heart of these technologies are membranes that control the transport of protons and other species—but today’s proton exchange membranes rely heavily on PFAS-based materials such as Nafion®. We are looking for a PhD candidate to develop a new generation of high-performance, PFAS-free proton-conductive membranes. In this project, you will combine the unique properties of proton-conductive metal-organic frameworks (MOFs) with those of proton-conductive polymers to create innovative membrane materials. You will systematically investigate how molecular structure, composition, and membrane architecture determine proton transport and overall performance. Your research will span materials chemistry, membrane science, and electrochemistry. You will establish design principles for high-performance proton-conductive membranes and put your materials to the test in different electrolyser configurations. This is an opportunity to work at the interface of fundamental materials science and real-world energy technology, with the ambition to develop membrane materials that can help enable a cleaner and more sustainable chemical industry. The PhD students will be supervised by Dennis Hetterscheid (Leiden Institute of Chemistry).

We also offer: An employment contract for 12 months initially, to be extended for 3 more years upon satisfactory performance. This contract falls under the CLA of Dutch Universities; A salary between €3,204 and €4,051 gross per month, based on a full-time appointment (38 hours - PhD student); A holiday allowance (8%), an end-of-year bonus (8.3%), and an attractive pension scheme at ABP; Full reimbursement of public transport commuting costs for home-to-work travel; Flexible working hours: as a standard, you are entitled to a minimum of 29 leave days on the basis of a full-time working week of 38 hours; you can also save for extra leave, for example by working 40 hours a week, and in this way accrue an extra 96 leave hours, or exchange 96 leave hours for a 36-hour week. Lots of options when it comes to secondary employment conditions; we can, for example, discuss options for paid parental leave. Within our terms of employment individual choices model, you can exchange leave days and/or salary for benefits such as an advantageous sports subscription and bicycle scheme; If your work allows it, hybrid working is possible within the Netherlands; A home-working allowance (day and internet allowance) and attention for good workplaces.
