Helmholtz-Zentrum Berlin is establishing a Helmholtz Young Investigator Group for electrochemical conversion of carbon dioxide
Dr. Matthew Mayer
Dr. Matthew T. Mayer from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, will be putting together a Helmholtz Young Investigator Group in the field of energy materials research at HZB. He will be researching into how carbon dioxide and water can be converted electrochemically into hydrocarbons such as methane and methanol using renewable energies. Matthew Mayer will receive 300,000 euros per year over a period of five years for establishing and running his Young Investigator Group.
Researchers are faced with the major challenge of developing new solutions for reducing the harmful emissions of carbon dioxide into our environment. One feasible solution is to use clean energy that will convert carbon dioxide and water electrochemically into hydrocarbons such as methane, methanol and ethylene, which are important raw materials for the chemical industry. The biggest hurdle will be improving the energy efficiency, reaction rates and yields from CO2 catalysis.
Research chemist Matthew T. Mayer is looking to produce novel electrocatalyst materials possessing heterogeneous bimetallic surfaces. Using synchrotron, X-ray and photoelectron spectroscopy, he will be observing these catalytic processes in situ and in operando in order to reveal detailed chemical information about the catalyst–molecule interactions in real time. In this way, Mayer wishes to deliver new insights into guided catalyst design, catalytic mechanisms and principles of cell design. These insights should help to reveal the potential of electrochemical CO2 reduction as a technology for producing valuable hydrocarbons.
“With Dr. Matthew Mayer, we are gaining a highly distinguished scientist whose field of research superbly complements our projects in energy materials research. His work will benefit from the many facilities for analysis and synthesis at HZB, and especially from their combination with the brilliant X-ray light from BESSY II,” says Prof. Dr. Anke Kaysser-Pyzalla, scientific director of HZB.
Matthew T. Mayer is from the U.S., where he studied chemistry at Boise State University and earned his doctorate at Boston College. He currently heads the “Solar Fuels” group at the Laboratory of Photonics and Interfaces, led by Prof. Dr. Michael Graetzel at the École Polytechnique Fédérale de Lausanne. In this group, Matthew T. Mayer is investigating how sunlight can be converted directly into fuels. Prior to this, he conducted research for several years at Boston College in the USA. He holds two patents and has published numerous papers. He will be arriving at HZB to put together his Young Investigator Group in May 2017.
Two new Helmholtz Young Investigator Groups kick off in 2017
In 2016, HZB was especially successful in bidding for Helmholtz Young Investigator Groups. In a highly competitive process with 49 applications, thirteen new Young Investigator Groups in the Helmholtz Association were approved, two of which are from HZB. Alongside Matthew T. Mayer, HZB has acquired Dr. Antonio Abate, whose Helmholtz Young Investigator Group aims to improve the long-term stability of perovskite solar cells.
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.
- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- New instrument at BESSY II: The OÆSE endstation in EMILA new instrument is now available at BESSY II for investigating catalyst materials, battery electrodes and other energy devices under operating conditions: the Operando Absorption and Emission Spectroscopy on EMIL (OÆSE) endstation in the Energy Materials In-situ Laboratory Berlin (EMIL). A team led by Raul Garcia-Diez and Marcus Bär showcases the instrument’s capabilities via a proof-of-concept study on electrodeposited copper.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
