Doctoral Position (f/m/x) Chemistry - N2 Reduction through TiO2 Aerogels

Institut of Inorganic and Materials Chemistry

We are one of the largest and oldest universities in Europe and one of the most important employers in our region. Our broad range of subjects, the dynamic development of our main research areas and our central location in Cologne make us attractive for students and researchers from around the world. We offer a wide range of career opportunities in science, technology, and administration.

Professor Dr Milow’s Nanostructured Cellular Materials group focuses on the synthesis of highly porous, open-pored, and nanostructured materials known as aerogels. These materials possess many advantageous properties, such as high sound absorption and extremely low thermal conductivity, making them highly attractive materials with applications in many different fields, such as super-insulation materials in the aerospace, automotive, and building services industries.

The University of Cologne promotes equal opportunities and diversity. Women will be considered preferentially in accordance with the Equal Opportunities Act of North Rhine-Westphalia (Landesgleichstellungsgesetz - LGG NRW). We also expressly welcome applications from all suitable candidates regardless of their gender, nationality, ethnic and social origin, religion, disability, age, personal orientation and identity.

The position is available from 1 November 2026 on a part-time basis (26,69 hours per week). The position is to be filled for a fixed term of 36 months. If the applicant meets the relevant wage requirements and personal qualifications, the salary is based on remuneration group 13 TV-L of the pay scale for the German public sector.

Please apply online with proof of the required qualifications without a photo under: https://jobportal.uni-koeln.de. The reference number is Wiss2608-14. The application deadline is 15 September 2026.
