  Isotope Studies in Oxidation of Propane over Vanadium Oxide

Pierre Kube, Benjamin Frank, Robert Schlögl, and Annette Trunschke

ChemCatChem, 2017, 9, 3446 – 3455.
DOI: 10.1002/cctc.201700847

Roadmap to value or waste: The reaction network of propane oxidation over vanadium oxide catalysts was analyzed by using temperature-programmed reactions and experiments with D- and 13C-labeled propane molecules. Propylene formation and oxidation of acrolein strongly depend on the nature of the catalyst. Surface density of vanadyl groups and nature of electrophilic oxygen species are relevant with regard to selectivity.

  A combined experimental and theoretical spectroscopic protocol for the determination of the structure of heterogeneous catalysts: Developing the information content of the resonance Raman spectra of M1 MoVOx

Adam Kuba, Johannes Noak, Annette Trunschke, Robert Schlögl, Frank Neese, and Dimitrios Maganas

Chemical Science, 2017, 8, 6338–6353.
DOI: 10.1039/C7SC01771E

In this work, we study the absorption and resonance Raman spectra of the M1 MoVOx catalyst. It is shown that due to the local nature of the involved electronic transitions, band assignment protocols developed for molecular systems can be applied to describe the calculated spectral features of the cluster models as well.

Selective Alkane Oxidation by Manganese Oxide: Site Isolation of MnOx Chains at the Surface of MnWO4 Nanorods

Xuan Li, Thomas Lunkenbein, Jutta Kröhnert, Verena Pfeifer, Frank Girgsdies, Frank Rosowski, Robert Schlögl, and Annette Trunschke

Angewandte Chemie, International Edition 2016, 55, 4092.
DOI: 10.1002/anie.201510201

Site isolation of surface manganese oxide species was obtained by the hydrothermal synthesis of nanostructured MnWO4. In contrast to manganese oxide, which is a combustion catalyst, MnOx chains on the exposed (010) crystal plane of MnWO4 selectively catalyze the oxidative dehydrogenation of propane to propene.
