Publication alertCatalytic Activity of Individual Particles
Analyzing tiny nanoparticles separately is a challenge. The working groups of A2 and C3 developed a new technique using electron microscopy and a robotic arm that could make the process much easier. The journal "Angewandte Chemie" covers the method in its latest issue.

05.11.2020Beatriz Roldán Cuenya received Paul H. Emmett Award
Prof. Dr. Beatiz Roldán Cuenya has been announced as the 2022 winner of the Paul H. Emmett Award in Fundamental Catalysis by the North American Catalysis Society.
"Professor Roldan has made exceptional contributions to the mechanistic understanding of thermal and electro-catalytic reactions based on the use of well-defined nanostructured materials combined with advanced in situ and operando microscopic and spectroscopic characterization. Her challenging experimental catalytic [catalysis] research has greatly advanced our fundamental knowledge of how geometric and electronic properties influence the catalytic performance. In particular, she has provided insight into re-utilization of CO2 through its thermal or electrochemical conversions to higher value chemicals and fuels such as methanol, ethylene, or ethanol. A highlight of her research program are studies featuring the dynamic nature of nanocatalysts under reaction conditions using synchrotron-based operando spectroscopy and diffraction methods combined with environmental transmission electron microscopy. She has pioneered the combination of colloidal chemistry approaches and electrochemical synthesis for the preparation of model catalytically active materials, and their chemical functionalization and restructuring using plasma treatments. Overall, her work has served to bridge the gap between surface science and “real” catalysis by creating scalable ex situ synthesis approaches leading to monodispersed nanomaterials and exposing them to in depth physico-chemical characterization under realistic reaction conditions. Her research will help to guide the rational design of the next generation of catalysts based on atomistic understanding."

Publication alertThorough assessment of activity trends for electrocatalyzed processes: Beyond the thermodynamic overpotential
An important criterion for the suitability of electrocatalysts, based on non-scarce elements, corresponds to their activity for electrocatalyzed processes. Ab-initio theory by the application of density functional theory calculations has been established as a standard tool to comprehend activity trends of potential electrode compositions in a class of materials by simple thermodynamic considerations, applying the so-called thermodynamic overpotential as activity descriptor. In a recent viewpoint in ACS Catalysis, Dr. Kai Exner from the University of Duisburg-Essen has demonstrated that the conventional picture is too simplistic, thereby introducing a universal descriptor Gmax(η) for the assessment of electrocatalytic activity, which takes the applied overpotential into account and mimics the kinetics of the reaction by referring to the free-energy span model.

Jointly promoting catalysis researchResearchers from Germany and Austria met for the first interdisciplinary conference
Catalysis initiates central processes of our entire life on earth - from enzyme catalysis in metabolic processes in all organisms to natural photosynthesis and the production of synthetics and environmentally friendly energy sources. Scientists in four Collaborative Research Centres (CRCs) of the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) are currently investigating how these fundamental and at the same time diverse processes of chemical catalysis work exactly and how their principles can be used for sustainable value creation.
In order to set new research impulses and create synergies in the field, the four DFG-funded Collaborative Research Centres have now organised the first joint CataLysis conference. Around 170 researchers from Germany and Austria presented their latest research findings in a joint online conference from September 30th to October 1st, 2020 and initiated new collaborations.
The participants presented their research topics in 16 lectures and 65 poster contributions. The spectrum ranged from homogeneous and heterogeneous catalysis, thermal catalysis and photocatalysis to (photo-) electrochemistry. The researchers also exchanged the latest findings on the methodological and theoretical characterisation of catalysis processes and on new materials and methods. After the sessions there was the possibility to meet and discuss with the speakers in a virtual room. Other virtual networking areas such as the Coffee Point or the Snack Bar offered additional opportunities to exchange ideas and initiate cooperation.
The speakers of the Collaborative Research Centres closed the conference with a positive summary: "We are thrilled to see the different and interesting developments that have emerged within catalysis research," said Prof. Michael Buchmeiser, spokesperson of CRC 1333. And Prof. Malte Behrens, spokesperson of CRC/TRR 247, added: "In order to be able to create synergies and make catalytic processes usable for important applications in the future, it is necessary to continue to illuminate this complex and multifaceted research area from all sides." Prof. Sven Rau, spokesperson of the CRC/TRR 234, is particularly pleased about the high participation of doctoral students who used this event for discussion and networking, underlining the importance of training for the sustainable catalysis research. In summary, Prof. Christian Jooss, spokesperson of CRC 1073, adds that the common goal is to link the methodologies and approaches even more strongly in the future than in the past and beyond the boundaries of the respective Collaborative Research Centres.
The spectrum of the field of catalysis is reflected in the topics of the Collaborative Research Centres:
- CRC 1333: "Molecular Heterogeneous Catalysis in Confined Geometries"
- CRC/TRR 247: "Heterogeneous Oxidation Catalysis in the Liquid Phase - Materials and Mechanisms in Thermal, Electro- and Photocatalysis"
- CRC 1073: "Atom Scale Control of Energy Conversion"
- CRC/TRR 234: "CataLight - Light-driven Molecular Catalysts in Hierarchically Structured Materials: Synthesis and Mechanistic Studies"
30.09.-01.10.20Joint catalysis conference "CataLysis"
Together with the CRC/TRR 234, the CRC 1333 and the CRC 1073, we organized a joint catalysis conference. Due to Covid-19, the conference took place online.

Publication alertCatalyst deposition on fragile chips
Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst particles to tiny electrodes. It is inexpensive, simple and quick to perform. In order to characterize catalysts and test their potential for various applications, researchers have to fix the particles to electrodes so that they can then be examined, for example, with transmission electron microscopy.

07.02.2020Tong Li appointed as professor at the Ruhr-University Bochum
To develop high-performance catalysts, not only good production processes are needed, but also good methods to characterize the potential catalysts. The latter is the main research interest of Tong Li, who already worked on this topic as a junior professor at the RUB. Since February 7, 2020, she has been a professor for the characterization of high-performance materials on the atomic scale.
Tong Li is an expert in atomic probe tomography. With this method in combination with transmission electron microscopy, she can make the structure of materials visible atom by atom.
