Three signals have been observed at 24.5, −12 and −42 ppm (reference external liquid ammonia) which are assigned to chemisorbed ammonia species RuNHx. Sample exposure to vacuum or aging leads to conversion of the 24.5 ppm species into the other ones, a process which is reversed by re-exposure to hydrogen gas. Exposure to a mixture of 15NH3 and 13CO leads to the formation of surface bound urea as demonstrated by 15N and 13C CP MAS NMR. To understand the surface reactions of ammonia and the 15N NMR results, quantum chemical calculations of the structures, energies and 15N chemical shifts of ammonia species on Ru6 and Ru55 model clusters have been performed. The calculations indicate that under the experimental conditions applied, the fractions of RuNH3 and RuNH2 species are similar, independent of the H2 pressure. No RuN and RuNH species are formed which are calculated to resonate at a lower field than the signals observed experimentally. However, the 15N chemical shifts of RuNH2 depend on the number of neighboring surface hydrogens and hence on the H2 pressure. Thus, the signal at 24.5 ppm is assigned to RuNH2 in a neighborhood rich in surface hydrogens. RuNH2 depleted in neighboring surface hydrogens and RuNH3 resonated both in a similar chemical shift range to which the signals at −12 and −42 belong. A change of the hydrogen pressure then leads to interconversion of hydrogen-rich and hydrogen-poor neighborhoods of RuNH2 but does not alter the fractions of RuNH3 and RuNH2 according to the calculated stability diagram. Nevertheless, dissociation of RuNH3 into RuNH2 and surface hydrogen is expected to take place during the initial ammonia adsorption process and at low H2 pressures and high temperatures. Finally, some preliminary quantum chemical calculations suggest stepwise binding of two NH2 groups to adsorbed CO leading to surface bound urea where the oxygen is coordinated to Ru.","lang":"eng"}],"extern":"1","publication":"Catalysis Science & Technology","issue":"13","doi":"10.1039/D0CY02476G","language":[{"iso":"eng"}],"intvolume":"        11","date_updated":"2026-02-17T16:13:50Z","author":[{"last_name":"Rothermel","first_name":"Niels","full_name":"Rothermel, Niels"},{"first_name":"Hans-Heinrich","last_name":"Limbach","full_name":"Limbach, Hans-Heinrich"},{"full_name":"Del Rosal, Iker","first_name":"Iker","last_name":"Del Rosal"},{"full_name":"Poteau, Romuald","first_name":"Romuald","last_name":"Poteau"},{"full_name":"Mencia, Gabriel","first_name":"Gabriel","last_name":"Mencia"},{"full_name":"Chaudret, Bruno","last_name":"Chaudret","first_name":"Bruno"},{"last_name":"Buntkowsky","first_name":"Gerd","full_name":"Buntkowsky, Gerd"},{"full_name":"Gutmann, Torsten","last_name":"Gutmann","first_name":"Torsten","id":"118165"}],"publication_identifier":{"issn":["2044-4753"]},"year":"2021","title":"Surface reactions of ammonia on ruthenium nanoparticles revealed by 15N and 13C solid-state NMR","citation":{"short":"N.

XPS data demonstrate that the oxidation state of rhodium in the dirhodium nodes is maintained during the synthesis of the polymers. The coordination polymers have been further characterized by FTIR, 1H → 13C CP MAS NMR and 19F MAS NMR spectroscopy to prove the formation of polymers via ligand exchange. Although the quantitative 19F MAS NMR spectra reveal incomplete ligand substitution in the coordination polymers, these catalysts show excellent activity and selectivity in the asymmetric cyclopropanation reaction between styrene and diazooxindole. In particular, the enantioselectivity has been significantly improved compared with previously designed dirhodium coordination polymers, which were synthesized from aromatic dicarboxylic acids derived from l-phenylalanine.

DNP signal enhancement factors up to 170 enable gaining deeper insight into the surface chemistry of Pt-NPs. Carbon monoxide is used as a probe molecule to analyze the adsorption process and the surface chemistry on the supported Pt-NPs. The studied systems show significant catalytic activity in carbon monoxide oxidation on their surface at room temperature. The underlying catalytic mechanism is the water-gas shift reaction. In the case of alumina as the support the produced CO2 reacts with the surface to form carbonate, which is revealed by solid-state NMR. A similar carbonate formation is also observed when physical mixtures of neat alumina with silica, fumed silica and titania supported Pt-NPs are studied.","lang":"eng"}],"extern":"1","date_created":"2026-02-07T15:47:21Z","type":"journal_article","keyword":["Chemistry","gamma-alumina","hydrogenation","silica","c-13","interactions","metal-catalysts","particle-size","platinum nanoparticles","sites","surface","water-gas shift"],"title":"Room temperature CO oxidation catalysed by supported Pt nanoparticles revealed by solid-state NMR and DNP spectroscopy","year":"2019","author":[{"full_name":"Klimavicius, V.","first_name":"V.","last_name":"Klimavicius"},{"full_name":"Neumann, S.","first_name":"S.","last_name":"Neumann"},{"first_name":"S.","last_name":"Kunz","full_name":"Kunz, S."},{"full_name":"Gutmann, Torsten","last_name":"Gutmann","first_name":"Torsten","id":"118165"},{"last_name":"Buntkowsky","first_name":"G.","full_name":"Buntkowsky, G."}],"publication_identifier":{"issn":["2044-4753"]},"date_updated":"2026-02-17T16:16:33Z","intvolume":"         9","language":[{"iso":"eng"}],"doi":"10.1039/c9cy00684b","citation":{"mla":"Klimavicius, V., et al. “Room Temperature CO Oxidation Catalysed by Supported Pt Nanoparticles Revealed by Solid-State NMR and DNP Spectroscopy.” <i>Catalysis Science &#38; Technology</i>, vol. 9, no. 14, 2019, pp. 3743–3752, doi:<a href=\"https://doi.org/10.1039/c9cy00684b\">10.1039/c9cy00684b</a>.","bibtex":"@article{Klimavicius_Neumann_Kunz_Gutmann_Buntkowsky_2019, title={Room temperature CO oxidation catalysed by supported Pt nanoparticles revealed by solid-state NMR and DNP spectroscopy}, volume={9}, DOI={<a href=\"https://doi.org/10.1039/c9cy00684b\">10.1039/c9cy00684b</a>}, number={14}, journal={Catalysis Science &#38; Technology}, author={Klimavicius, V. and Neumann, S. and Kunz, S. and Gutmann, Torsten and Buntkowsky, G.}, year={2019}, pages={3743–3752} }","ama":"Klimavicius V, Neumann S, Kunz S, Gutmann T, Buntkowsky G.

The individual lamellae of the dirhodium-bdc frameworks are stacked as parallel sheets, which are randomly oriented or slightly ordered. As inorganic building blocks Rh2(TFA)4 and Rh2(OAc)4, and as organic linker benzene 1,4-dicarboxylate (bdc) are employed. The successful synthesis of the Rh2-bdc(Tf) and Rh2-bdc(Ac) catalysts is proven by ATR-IR, XPS and 13C CP MAS NMR. Residual trifluoroacetate species are investigated by quantitative 19F MAS NMR which further reflects the configuration of trifluoroacetate in the obtained Rh2-bdc(Tf), and defects in the structure. DR-UV-vis and XPS demonstrate that the oxidation state and the Rh-Rh single bond in the dirhodium node are maintained during the ligand substitution process. The stability and reusability of the catalysts are verified by TG-DTA measurements and leaching tests. The catalysts show similar catalytic efficiency as the homogeneous catalyst in the model cyclopropanation between ethyl diazoacetate (EDA) and styrene.","lang":"eng"}],"extern":"1","issue":"21","publication":"Catalysis Science & Technology"},{"language":[{"iso":"eng"}],"_id":"64026","page":"595–599","volume":3,"user_id":"100715","doi":"10.1039/c2cy20683h","author":[{"first_name":"Eoin","last_name":"Rafter","full_name":"Rafter, Eoin"},{"id":"118165","last_name":"Gutmann","first_name":"Torsten","full_name":"Gutmann, Torsten"},{"full_name":"Loew, Florian","first_name":"Florian","last_name":"Loew"},{"last_name":"Buntkowsky","first_name":"Gerd","full_name":"Buntkowsky, Gerd"},{"last_name":"Philippot","first_name":"Karine","full_name":"Philippot, Karine"},{"last_name":"Chaudret","first_name":"Bruno","full_name":"Chaudret, Bruno"},{"full_name":"van Leeuwen, Piet W.
