19.03.2018Regarding new emission standards, crucial challenges emerge for diesel engines. Due to their soot-free combustion in internal combustion engines, oxymethylene dimethyl ethers (OMEs) are promising fuel additives. The Synthesis of OMEs from dimethyl ether is an important step for a holistic OME production and was recently demonstrated at IKFT. The research is founded by Fachagentur Nachwachsende Rohstoffe e.V. (FNR) and conducted in collaboration with TU Kaiserslautern and TU Munich.

15.03.2018Research work from IKFT, and IMVT was highlighted in Chemical & Engineering News. By looking at a palladium catalyst while it converts hydrogen and oxygen to hydrogen peroxide, researchers have uncovered that α-palladium hydride nanoparticles were responsible for the selective hydrogenation of oxygen to hydrogen peroxide. “This is a very interesting study as it probes the nature of a palladium catalyst under operating conditions and clearly shows the potential role of various palladium hydrides in this challenging reaction,” says Graham J. Hutchings from Cardiff University.

08.02.2018Researchers at the IKFT have looked at a process that has the potential to oxidize methane selectively to methanol.
With a focus on copper-exchanged zeolite materials they suggest that an ideal methane activation catalyst represents a trade-off between stability and reactivity of the active site that can be achieved by tuning the transition metal cation, active site motif and the zeolite topology.

02.02.2018The project “Magnetic liquid crystalline hybrid materials: synthesis of anisotropic magnetic hybrid materials via organized integration of nanoparticles in liquid crystalline matrices” is funded by the German Science Foundation (DFG) during the third funding period of the priority program “Field controlled particle matrix interaction: synthesis, multi-scale modelling and application of magnetic hybrid materials” (SPP 1681). https://www.magnetofluiddynamik.de/spp1681/index.php/willkommen
17.11.2017The article Production of oxymethylene dimethyl ether (OME)-hydrocarbon fuel blends in a one-step synthesis/extraction procedure is now available online at #!authors.elsevier.com/c/1V-Dd3iH40KXD##ELSEVIER##.
27.10.2017A theoretical investigation of the initiation of the methanol-to-olefins (MTO) process identifies the formation of CO from methanol/DME and its further reaction in C-C coupling reactions as the most relevant of the studied mechanism. The full reaction mechanism from methanol to propylene is studied using DFT and additional corrections from ab initio calculations. The investigation also shows that a kinetic model of the autocatalytic reaction that follows initiation is essential to judge whether or not a mechanism is realistic. [Plessow, P. N.; Studt, F. ACS Catal. 2017]
19.09.2017Catalysis Science & Technology - Cover Article. Pt-based diesel oxidation catalysts were exposed to rapid transient temperature conditions based on a realistic driving cycle. A microreactor setup was used for rapid heating/cooling coupled to operando X-ray absorption spectroscopy and on-line mass spectrometry. Major differences in catalyst structure and performance were observed under transient conditions compared to model studies. Benzi, F.; Sheppard, T.L.; Doronkin, D.E.; Meira, D.M.; Gänzler, A.M.; Baier, S.; Grunwaldt, J.-D. Catal. Sci. Technol. 2017, 7, 3999-4006.
18.08.2017On 20. and 21. September 2017 a two day workshop dedicated to the inauguration of KIT´s new beamline for catalysis and actinide research (CAT-ACT) will take place in the ANKA seminar room (KIT Campus North, building 348, 1st floor, west entrance). CAT-ACT is jointly operated by the KIT institutes INE (for radionuclide science) and IKFT/ITCP (for catalysis research). The workshop will highlight research activities and access possibilities at CAT-ACT and particularly cover the following topics: Introduction to CAT-ACT and lab infrastructure, overview and highlight talks on XAS in Catalysis and Actinide research, involved KIT/HGF research programs, KIT in-house research activities and projects with cooperation partners, and future research perspectives. Preceding the workshop a two days training course providing an overview on XAFS methods, theory and data analysis will be offered. Registration deadline is 1 September 2017.

07.08.2017The EU project ‘Brisk – Biofuels Research Infrastructure for Sharing Knowledge’ has returned for 2017. BRISK2 will fund researchers to carry out training research and this time IKFT participates by offering three pilot plant facilities: fast pyrolysis, hydrothermal liquefaction, and hydrodeoxygenation of bio-oil. Calls to apply for projects will open twice a year until 2021. More details are available here: http://www.brisk2.eu/
06.07.2017Cutting-edge synchrotron X-ray tomography was applied to image catalysts at work. The structure of a core@shell catalyst for direct synthesis of dimethyl ether (DME) was detailed in 3D, in situ and simultaneously by X-ray diffraction, fluorescence and absorption tomography; revealing important information about catalyst structure and function which is unavailable using conventional methods. Sheppard, T.L.; Price, S.W.T.; Benzi, F.; Baier, S.; Klumpp, M.; Dittmeyer, R.; Schwieger, W.; Grunwaldt, J.-D. J. Am. Chem. Soc. 2017, 139, 7855-7863.

28.06.2017The „Wissenschaftliche Gesellschaft für Kraftfahrzeug- und Motorentechnik (WKM)“ has published a statement concerning the future of the internal combustion engine. 25 experts of the WKM, Prof. Gauterin and Prof. Koch from KIT among them, gave insides based on scientific facts on the measurement technologies for off-gas-composition of automobiles and the environmental impact of emissions of internal combustion engines.
22.06.2017The doctoral students of IKFT and IMVT were present with a joint stand at the annual summer festival of the Fachschaft MACH/CIW at Campus South. The selection of drinks (Gin Tonic and Cider) was well received by the guests and the staff and contributed to a completely successful evening.
21.06.2017Oxymethylene dimethyl ethers (OMEs) are investigated at IKFT as promising fuel additives that are accessible from renewable resources. A recent computational study from theory and model systems investigated the mechanism for the synthesis of OMEs from trioxane and dimethoxymethane. The results explain the observed experimental selectivity that initially favors OME4 and is eventually controlled thermodynamically. [Goncalves, T. J.; Arnold, U.; Plessow, P. N.; Studt, F. ACS Catalysis 2017, 7, 3615–3621.]
17.05.2017An Interview with Prof. Jörg Sauer was broadcasted as part of a program about Diesel fuels and oxymethylene dimethyl ethers on Deutschlandfunk.

17.05.2017The computational prediction of the rotational spectrum of the CaH+ molecular ion, taking into account coupling with the 1H nuclear spin and external magnetic fields, has contributed to the realization of ground-braking experiments at the National Institute of Standards and Technology (NIST). Single molecules have been prepared in pure quantum states and were subsequently manipulated. [Chou, C.-W.; Kurz, C.; Hume, D. B.; Plessow, P. N.; Leibrandt, D. R.; Leibfried, D.
