Fraunhofer IMM

Senior scientist Dr. Thomas H. Rehm is team leader at IMM and coordinator of the CarbonCat project. He was educated at Julius-Maximilians-Universität Würzburg and received his diploma and PhD in supramolecular polymer chemistry. During two PostDoc stays he worked on dye chemistry and related photophysical phenomena. Finally, he joined IMM in 2011 and started to work on flow chemistry with microstructured reactors and equipment in the fields of hydrogenation, catalyst immobilisation, online-NMR analysis and photochemical catalysis.

Based on the expertise in the development and exploration of microstructured reactors Fraunhofer IMM will realize a continuously operating reactor plant whose core will be the novel diamond photocatalyst. The physical adaptation of the diamond material applied in the micro reactor as well as the detailed investigation of the photocatalytic process in continuous operation mode is also part of IMM’s tasks.

Julius-Maximilians-Universität Würzburg

Professor Krueger’s research group at the Julius-Maximilians-Universität Würzburg is working on the fabrication, characterization and utilization of nanoscale carbon-based materials, especially diamond, for more than 10 years. One of their current working focuses is the Horizon2020 project DIACAT, which deals with the fundamental research on photocatalytic applications with solvated electrons from diamond surfaces. Furthermore, Prof. Krueger and her research group developed numerous novel methods for achieving exceptional stable bonds between functional molecules and diamond surfaces. CarbonCat will make use of these methods to optimize the diamond material for its use as photocatalyst in the micro reactor. The development of the photocatalytic conversions of CO2 in a flask as well as their analytics is task of Prof. Krueger’s team in the project.

Sahlmann Photochemical Solutions

Dr. Benjamin Sahlmann works as a freelance chemist developing highly specialized light sources and experimental setups for photochemical applications since May 2013. After receiving a diploma in chemistry from the Christian-Albrechts-Universität in Kiel, he started writing his PhD thesis in context of the Collaborative Research Center 677 “Function by Switching”, developing photoswitchable ion carriers. During the research in this and neighbouring CRC projects, most light sources available at the market held disadvantages or had to be adjusted laboriously. As a consequence, he started manufacturing specialized photochemical light sources for scientific applications based on high-power LEDs mainly. As a logical consequence, he pursued the set-up of an own business after obtaining his PhD and achieved an Exist Business Start-Up Grant. Since then he offers his clients expertise and solutions to all photochemistry related issues.
Dr. Benjamin Sahlmann will provide the light sources for both the development process of the catalyst at Würzburg University and its implementation in the microreactor at the Fraunhofer IMM Mainz. Additionally, both project partners will be consulted regarding the optimization of the photochemical process as well as training and advice for Occupational Safety and Health.
