KJEMI nr. 1 - 2023

1 0 K J E M I 1 2 0 2 3 Unfortunately, the first invited speaker, Professor Yi Cui from Stanford University had to cancel due to illness. His original talk was entitled: «Tuning Electrocatalysts for Clean Energy». Hopefully, there will be another opportunity to learn more about this exciting topic on a future event. Hilde Venvik (NTNU) was graciously able to step in on short notice and gave a talk entitled: «In situ NAP-XPS characterization of PdAg hydrogen membranes and catalytic model system». Hilde gave a presentation on developments made at the HIPPIE beamline at the MAXIV synchrotron in Lund, Sweden. The near ambient pressure X-ray photoelectron spectroscopy method is maturing, and she showed insights obtained for Pd and PdAg catalysts for CO oxidation. Moreover, the approach has been extended also to investigate hydrogen gas separation with membranes of the same materials. The second talk was given by Terje Hauen from SEID. SEID is a company with headquarters near Sandnes that specializes in low temperature plasma reactors. SEID has decades of experience with making ozone from oxygen, and also with nitrogen activation. Recent developments were in the area of methane decomposition into hydrogen gas and carbon black. Hongfei Ma (NTNU) gave a presentation related to the upgrading of biomass derived lignin oils. Using model molecules, he was able to derive a reaction network for the hydrodeoxygneation reaction. Sebastian Prodinger (UiO, in collaboration with Haldor Topøe A/S within the iCSI center) presented recent progress towards controlling the Al location in mordenite zeolite frameworks using inorganic templating. Both the choice of anion in the aluminum source and the cation in the hydroxide (sodium or potassium) have profound influence on the preferred Al substitution sites. Mouhammad Abu Rasheed (UiO, in the context of the ERC-SYNERGY CUBE project) has taken inspiration from enzyme catalysis to develop copper based complexes that can catalyze the selective oxidation of cyclohexane. Francesca L. Bleken (SINTEF, in collaboration with ELKEM) presented theoretical investigations of methyl chloride decomposition on copper surfaces and silicon doped copper surfaces. This is an important step in the manufacturing of silicone products. Eight presentations After lunch, the program comprised eight presentations. Izar Capel Berdiell (UiO, in collaboration with Haldor Topøe A/S) showed recent progress in the use of operando X-ray diffraction methods to monitor the deactivation of a working zeolite catalyst during the conversion of methanol to hydrocarbons. Ask Lysne (NTNU, within the context of FME Bio4Fuels) discussed the development of a nickel cobalt catalyst that was resistant to tar and tar compounds in steam reforming of biomass derived syngas. Evgeniy Redekop (UiO) highlighted the use of transient methods and the TAP reactor to study reaction kinetics. He also presented recent developments at the FinEstBeaMS beamline at MAXIV in photoionization based mass spectrometry for isomer selective product analyses. Raquel Jimenez Rama (UiO) presented a mechanistic study of palladium-­ catalyzed C-N couplings. Using both experiment and theory, Raquel has proposed a catalytic cycle and determined the resting state of the catalyst. Torstein Fjermestad (UiO) presented a multiscale The Norwegian Catalysis Symposium 2022 The 2022 Norwegian Catalysis Symposium was organized in Stavanger December 1-2. 2022. This was the first time the symposium was held in Stavanger, and the board of the Catalysis Division would like to commend Professor Zhixin Xu on an excellent event! The event gathered 39 participants from the Norwegian catalysis community, representing 6 different institutions and 1 company, including NTNU, Universities of Stavanger, University of Oslo, IFE, SINTEF, NORCE, SEID AS. Professor Zhixin Xu and Professor Stian Svelle
