Two new Helmholtz Young Investigator Groups will start in 2019
Starting in 2019, Helmholtz-Zentrum Berlin (HZB) will be establishing two new Helmholtz Young Investigator Groups and thereby strengthening its competencies in catalysis research. The Helmholtz Association will be funding each group with 150,000 euros annually over a period of five years, and HZB will be matching that sum with its own funds.
The group of Dr. Christopher Seiji Kley will be developing light-absorbing materials and catalysts for the sunlight-driven conversion of carbon dioxide and water into fuels. The Young Investigator Group will be introducing concepts inspired from biology as a way to increase the catalysts’ energy efficiency and to maximise the catalytic activity for longer-chain hydrocarbons. The planned start for the group is in March 2019.
Dr. Olga Kasian’s group will be researching what are the factors currently limiting the performance of catalysts in solar hydrogen production. To do so, they will be analysing the catalysts’ uppermost atomic layers and explaining the reaction mechanisms by directly detecting the intermediates and products. BESSY II offers the latest spectroscopic methods for studying the electronic changes in the materials in-operando. Olga Kasian’s Young Investigator Group will kick off in May 2019.
Two out of ten new Helmholtz Young Investigator Groups at HZB
In the recent selection process for heads of Young Investigator Groups, an interdisciplinary jury selected ten talents from a total of 23 applicants. HZB came out very successfully in the selection round: out of ten newly funded Helmholtz Young Investigator Groups, two are to be established at HZB in 2019.
About the “Helmholtz Young Investigators” programme
The research programme fosters highly qualified young researchers who completed their doctorate three to six years ago. The heads of the Young Investigator Groups receive support through a tailored training and mentoring programme and are assured long-term prospects at HZB. One aim of the programme is to strengthen the networking of Helmholtz centres and universities. The costs – 300,000 euros per year per group over five years – are covered half by the Helmholtz President’s Initiative and Networking Fund, and half by the Helmholtz centres.
- Porous Radical Organic framework improves lithium-sulphur batteriesA team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.
- Metallic nanocatalysts: what really happens during catalysisUsing a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behaviour of nanocatalysts during catalysis. The nanoparticles consisted of a platinum core with a rhodium shell. This configuration allows a better understanding of structural changes in, for example, rhodium-platinum catalysts for emission control. The results show that under typical catalytic conditions, some of the rhodium in the shell can diffuse into the interior of the nanoparticles. However, most of it remains on the surface and oxidises. This process is strongly dependent on the surface orientation of the nanoparticle facets.
