PhD position: Structure-activity relationships for CO2 capture materials100%, Zurich, fixed-termThe Laboratory of Energy Science and Engineering (LESE, ETH Zürich) invites applications for a PhD position in the field of CO2 capture, with a focus on structure–performance relationships. At LESE, our research aims to obtain a fundamental understanding of materials that allow for the capture and/or conversion of CO2. This PhD position is funded by the National Centre of Competence in Research (NCCR) Separations.Job descriptionWithin a broader research program that integrates process modelling, computational materials screening and discovery, experimental synthesis, and mechanistic and performance assessment under application-relevant conditions for separation technologies, this project aims to accelerate the identification of novel materials for CO2 capture Specifically, this PhD project combines the synthesis of model materials as well as their operando characterization and molecular modelling to identify new CO2 sorbent families and to establish structure–performance relationships Concerning the experimental techniques employed, this PhD position will focus on (operando) X-ray absorption spectroscopy, X-ray total scattering, and vibrational spectroscopies ProfileApplicants for this PhD position are expected to have an excellent MSc degree in Chemical Engineering, Material Science, or Chemistry Experience and knowledge in material synthesis and/or (structural) material characterization are highly valued We are looking for highly motivated, committed, and creative individuals who can work in a team and have outstanding communication skills Working in a top-level research environment with advanced laboratory infrastructure, the candidate will have a unique opportunity to develop their research abilities The position is available from May 2026 onwards WorkplaceWorkplaceWe offerAn exciting working environment Opportunities to learn cutting edge techniques Perspectives for career development A diverse and interdisciplinary team We value diversity and sustainabilityCurious?
