Cathleen Zeymer and Laerte Patera receive ERC Starting Grants
Congratulations to Cathleen Zeymer and Laerte Patera, Associated Researchers at the CRC, for both having received an ERC Starting Grant! The ERC Starting Grants are Europe's most prestigeous funding source for young researchers at the start of their independent academic careers.
With her project "Artificial Lanthanide Enzymes for Selective Photocatalysis" (PhotoLanZyme) Cathleen Zeymer wants to develop artificial enzymes for reactions that go beyond the nature’s synthetic repertoire. Her team targets the synthesis of a new class of sustainable photocatalysts whose chiral environment enables stereoselective transformations In an evolutionary process, starting from simple proteins with lanthanide ions in their active site.
Laerte Patera's research interest is the artificial photosynthesis, which could make a decisive contribution to the portfolio of renewable energy sources, if the atomic-scale mechanisms were known precisely. With his project "Watching Excitons in Photoactive Organic Frameworks" (WEPOF), he aims at filling these gaps. He wants to develop microscopic methods with which the excited states generated by light in organic energy materials can be observed directly to be able to develop new, more efficient materials from the knowledge of the structure-function relationships.

Shigeyoshi Inoue receives the prestigeous ERC Consolidator Grant
Shigeyoshi Inoue is awarded with the ERC Consolidator Grant for his ALLOWE project on highly reactive low-valent aluminum complexes and their application in synthesis and catalysis. These compounds are highly reactive and therefore of great interest for chemical synthesis and catalysis. They could represent an inexpensive, sustainable and non-toxic alternative to industrial chemical processes currently based on transition metals.
Silvia Bordiga and Unni Olsbye are awarded with the TUM Wilhelm Manchot Professorship
The Manchot Foundation awards Prof. Silvia Bordiga (University of Turin) and Prof. Unni Olsbye (University of Oslo) with the 2019 Wilhelm Manchot Professorship for their contributions in catalysis research. Due to the COVID-19 situation, the award ceremony will take place in early 2021.
Silvia Bordiga uses spectroscopic methods in order to achieve a detailed understanding of the physicochemical nature of a large variety of nanostructured high surface area materials that find applications as heterogeneous catalysts, and to describe the structure and the number of the active sites; the reaction mechanisms; the origin of catalysts deactivationvia laboratory spectroscopies and advanced techniques available at the synchrotron beam lines in controlled atmosphere.
Unni Olsbye’s research interests are directed towards structure-composition-function correlations in catalytic reactions, such as methanol to hydrocarbons, methane partial oxidation to methanol and to syngas, light alkane dehydrogenation, methyl halide conversion, ethene oxychlorination, and CO2 conversion. The emphasis is set on mechanistic studies of target- and by-product formation, as well as studies of the influence of confinement effects in micro- and nanoporous materials.
The TUM Manchot Professorship has been awarded since 1991, commemorating the chemist Wilhelm Manchot, who has been professor and director of the Institute of Inorganic Chemistry at the Technische Hochschule München (now TUM) from 1914 to 1935. The Manchot Foundation traditionally invites the award recipients to lecture at the TUM Department of Chemistry.
Highly dynamic structural changes at the surface of copper electrocatalysts
The team of Karsten Reuter has found highly dynamic structural changes at the surface of working copper electrocatalysts. These changes turn out to be key to the high performance and could be a design target for future improved catalysts for splitting water into hydrogen or producing synthetic fuels. Unfortunately, presently these catalysts often consist of rare elements such as platinum or iridium, which are either very expensive to obtain or not available in the quantities needed for a global energy supply. Therefore, catalysis research is looking for more abundant alternatives.
In their work published in Nature Catalysis, the teams of Julia Kunze-Liebhäuser (University of Innsbruck) and Karsten Reuter show that during the electrooxidation reaction of carbon monoxide (CO) copper catalysts have their own solution to this problem. CO is an intermediate product that is produced during the conversion of fuels in fuel cells. To prevent the fuel cell from being poisoned, it must be disposed of through the electrooxidation reaction. During the reaction, the scientists observed that the copper surface is continuously converted and that small islands consisting of a few copper atoms are continuously formed. The charge of adsorbing ions gets stored in these protruding, nanometer-sized clusters. In the studied electrooxidation reaction in the used alkaline electrolyte this is especially the charge of the involved hydroxide (OH-) ions. This leads to fundamentally different binding properties to the catalyst than for the neutral reaction partner CO. The hydroxide ions are bound weaker, the CO stronger - exactly the mixture required for the observed high catalytic activity.
Hydrochloric acid treatment improves catalysts for removing sulfur from crude oil
The team of Johannes Lercher has developed a synthesis process which drastically increases the activity of catalysts for the desulfurization of crude oil. The new process could perhaps also be used for catalysts in fuel cells.
Online TUM-JST symposium „Catalysis Science – Quo Vadis” on July 27-28, 2020
The symposium “Catalysis Science – Quo Vadis” for early and mid-career scientists from Japan and Europe took place as an online webinar on July 27-28, 2020. Organized by Roland Fischer, Director of the CRC and Hiroshi Kitagawa (Kyoto University), Supervisor of the PRESTO (Precursory Research for Embryonic Science and Technology) Innocat program of the Japan Science and Technology Agency (JST), the symposium aimed to connect 19 emerging leaders in catalysis science from Japan with a matching selection of 20 early and mid-career scientists from Europe, with the purpose to get together, find common research interests and to build a transcontinental network.
Owing to the current COVID-19 situation, the scientists presented their research online, but in an unconventional way of tandem presentations. The core idea of this style was to form duets of Japanese and European researchers who would cross-present each other’s research in a flash talk of 5-10 min in total. This format promoted exchanging and discussion with the partner before the symposium and highlighted each other’s work and scientific contributions in a nice way. The Book of Abstracts of all participants is found here.
In the symposium, a wide variety of cutting-edge topics of catalysis science were introduced and discussed. The Chairmen Fischer and Kitagawa gave a message with positive expectation in the closing remarks, “We hope that this symposium will be a foothold to build an international network, and successfully lead to joint research. Furthermore, we are looking forward to meet again on the real CSQV conference after the COVID-19 will converge.”

Directed synthesis of a complex metal oxide with high activity
Design of highly active Mo-V-Te-Nb oxide catalyst for ODH is made possible by understanding the formation of active surfaces
MoVTeNb oxide catalysts are used for ethylene production via ethane oxidative dehydrogenation (ODH). Maricruz Sanchez-Sanchez and Johannes A. Lercher at the CRC work on the optimization of this type of materials for an industrial application, in collaboration with Clariant AG in the frame of the MuniCat alliance.
In situ electron microscopy studies at the Pacific Northwest National Laboratory in collaboration with Nigel Browning and Yuanyuan Zhu have yielded the atomic description of the active surface of a metal oxide catalyst and its dynamic response under reaction conditions. These studies, combined with reaction kinetics measured at the CRC, provided a direct relationship between the atomic configuration of the surface of an oxide and its catalytic activity. This level of understanding has enabled the researchers to design a new synthetic approach that proved successful in generating highly active metal oxides. This work has been published in September 2019 in Nature Communications.
Ultrasmall Pt clusters derived from Pt@MOF materials for the oxygen reduction
The electrocatalytic oxygen reduction (ORR) using a platinum catalyst is considered as the key to many energy applications, such as fuel cell technologies. In a joint effort the teams of Aliaksandr Bandarenka, Roland A. Fischer and Sebastian Günther from the CRC, Alessio Gagliardi from the TUM Department of Electrical and Computer Engineering, and Jan Macák from the CEITEC in Brno (Czech Republic) have achieved a breakthrough in preparing ultrasmall Pt clusters with optimal size for the efficient electrocatalytic ORR in proton-exchange-membrane fuel cells by combining theory and experiment. The results were published online on June 5, 2019 in Angewandte Chemie International Edition.
By utilizing a simple computational model, the mass activity of Pt clusters for ORR was predicted. The forecasted activities were affirmed with the experimental results for 1.1 nm sized Pt clusters, which were obtained by decomposition of Pt clusters embedded in the zeolitic imidazolate framework ZIF-8. The obteined Pt clusters exhibit a mass activity of 0.87 A mgPt-1 , which is one of the highest mass activities reported to date.
