PhD Position in Light-Driven CO2 Capture and Molecular Systems

100%, Zurich, fixed-term

print Drucken

The Electrochemical Energy Systems Laboratory at ETH Zurich is seeking a highly motivated PhD student to join our research on light-driven CO2 capture. Our group develops molecular systems that harness light to control chemical equilibria and enable energy-efficient carbon capture. By combining molecular design, physical chemistry, spectroscopy, and reaction engineering, we seek to uncover fundamental principles for next-generation responsive CO2 capture technologies.

Project background

Conventional CO2 capture technologies are energy intensive. This project explores an alternative concept in which light is used to control CO2 capture and release using photoresponsive molecular switches, photoacids. The research focuses on understanding how photoacids and related molecular switches influence proton transfer, chemical equilibria, and CO2 capture chemistry, with the goal of developing new approaches for energy-efficient carbon capture.

The project combines molecular synthesis, physical chemistry, spectroscopy, and reaction/process engineering to establish the mechanistic principles governing light-responsive CO2 capture systems.

Job Description

• Design and investigate molecular systems for light-driven CO2 capture
• Study photoinduced proton-transfer processes and their influence on CO2 capture chemistry
• Perform physicochemical characterization of molecular systems
• Analyze and interpret experimental data to develop mechanistic understanding
• Present your work at international conferences and publish your findings in leading scientific journals
• Collaborate closely with researchers within the group and with international collaborators

Profile

• You should hold (or be close to completing) a Master’s degree in Chemistry, Physical Chemistry, Organic Chemistry, Chemical Engineering, Materials Science, or a closely related discipline.
• We are looking for a highly motivated, curious, and self-driven researcher who enjoys tackling fundamental scientific questions and thrives in an interdisciplinary and collaborative environment

Experience in one or more of the following areas is advantageous, but not required:

• Physical chemistry or photochemistry
• Organic, polymer or supramolecular chemistry
• CO2 capture or reaction/process engineering
• Spectroscopic characterization techniques
