The iron modification of the silica was performed according to a frequently used impregnation technique from aqueous iron nitrate solution. The materials were characterized by nitrogen physisorption, X-ray diffraction, TEM–EDX, Moessbauer spectroscopy, and temperature-programmed reduction (TPR) and tested in the catalytic decomposition of methanol. It is established that the location and dispersion of iron oxide nanoparticles are affected by the pore topology of the support. The most homogeneously dispersed iron oxide nanoparticles are observed using silica host matrix exhibiting a 3-D channel-like structure and pore diameters about 7 nm, and the thus-obtained composites exhibit high catalytic activity and selectivity in methanol decomposition to CO and hydrogen. For all the samples, characterized with a low mesopore volume and small pore diameters/pore entrances, the formation of larger iron oxide particles, mainly located on the outer surface, is observed. Inhomogeneously dispersed iron oxide particles with a large fraction of isolated, strongly interacting with the support, iron species, and possessing low catalytic activity and usually high selectivity to methane, are found for the silicas with relatively larger pores/pore entrances.","lang":"eng"}],"extern":"1","publication":"Microporous and Mesoporous Materials","user_id":"23547","_id":"25980","page":"327-337","status":"public","quality_controlled":"1","citation":{"ieee":"T.

The effect of surface modification of the matrix pores, the choice of a solvent with suitable polarity, and the concentration of the metal nitrate solution are studied in detail. The efficiency of pore loading is monitored by nitrogen physisorption measurements. The creation of polar functions at the pore surface of CMK-3 carbon is shown to increase the impregnation efficiency substantially while maximizing the pore wall polarity of SBA-15 silica by increasing the amount of free silanol groups does not have any significant impact. The choice of a less polar solvent (THF instead of water) has a positive effect on the wettability of CMK-3 carbon in the first impregnation cycle but turns out to be disadvantageous in the second cycle; a similar trend is observed for variation of the metal salt concentration."}],"extern":"1","publication":"Microporous and Mesoporous Materials","user_id":"23547","_id":"25979","page":"575-582","status":"public","quality_controlled":"1","citation":{"mla":"Roggenbuck, Jan, et al. “Synthesis of Mesoporous Metal Oxides by Structure Replication: Strategies of Impregnating Porous Matrices with Metal Salts.” <i>Microporous and Mesoporous Materials</i>, 2008, pp. 575–82, doi:<a href=\"https://doi.org/10.1016/j.micromeso.2007.12.018\">10.1016/j.micromeso.2007.12.018</a>.","bibtex":"@article{Roggenbuck_Waitz_Tiemann_2008, title={Synthesis of mesoporous metal oxides by structure replication: Strategies of impregnating porous matrices with metal salts}, DOI={<a href=\"https://doi.org/10.1016/j.micromeso.2007.12.018\">10.1016/j.micromeso.2007.12.018</a>}, journal={Microporous and Mesoporous Materials}, author={Roggenbuck, Jan and Waitz, Thomas and Tiemann, Michael}, year={2008}, pages={575–582} }","ama":"Roggenbuck J, Waitz T, Tiemann M.

Methanol decomposition to hydrogen, CO, and methane was used as a catalytic test reaction. The obtained products exhibit uniform pores with a diameter of ca. 5 nm in a two-dimensional hexagonal periodic arrangement, as well as interparticle porosity, broadly distributed around ca. 35 nm; the specific surface area is 148 m2 g−1. The pore walls are polycrystalline. The polycrystalline nature and high surface-to-volume ratio of the products is reflected in an increased signal intensity in X-ray absorption spectroscopy. The synthesis of CeO2 from Ce(NO3)3 within the pores of the carbon matrix and the subsequent thermal combustion of the carbon is monitored by thermal analysis. Catalytic tests reveal that the activity of the mesoporous products in methanol decomposition are substantially higher than for a non-porous sample.","lang":"eng"}],"extern":"1","publication":"Microporous and Mesoporous Materials","type":"journal_article","department":[{"_id":"35"},{"_id":"163"},{"_id":"307"}],"date_created":"2021-10-09T09:41:24Z","date_updated":"2023-03-09T08:48:18Z","publication_status":"published","article_type":"original","title":"Mesoporous CeO2: Synthesis by nanocasting, characterisation and catalytic properties","year":"2007","author":[{"full_name":"Roggenbuck, Jan","first_name":"Jan","last_name":"Roggenbuck"},{"first_name":"Hanno","last_name":"Schäfer","full_name":"Schäfer, Hanno"},{"last_name":"Tsoncheva","first_name":"Tanya","full_name":"Tsoncheva, Tanya"},{"first_name":"Christo","last_name":"Minchev","full_name":"Minchev, Christo"},{"first_name":"Jan","last_name":"Hanss","full_name":"Hanss, Jan"},{"id":"23547","full_name":"Tiemann, Michael","last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722"}],"publication_identifier":{"issn":["1387-1811"]},"doi":"10.1016/j.micromeso.2006.11.029","language":[{"iso":"eng"}]},{"quality_controlled":"1","citation":{"ama":"Waitz T, Tiemann M, Klar PJ, Sann J, Stehr J, Meyer BK.

The average size, size distribution, and concentration of the particles are monitored within the sub-second time regime with a resolution of 1.28 ms. Particle growth at these early stages is governed by pronounced ripening. The UV absorption data strongly suggest that growth occurs by preferential adsorption of HS- anions relative to Zn2+ or ZnOH+ cations. Correspondingly, the initial sulfide concentration has a much more pronounced influence on the growth kinetics than the initial zinc concentration. These findings are verified by ζ-potential measurements which confirm that the particle surfaces are negatively charged under near-neutral pH conditions.","lang":"eng"}],"publication":"The Journal of Physical Chemistry B","doi":"10.1021/jp0638383","language":[{"iso":"eng"}],"article_type":"original","publication_status":"published","date_updated":"2023-03-09T08:56:40Z","publication_identifier":{"issn":["1520-6106","1520-5207"]},"author":[{"id":"23547","full_name":"Tiemann, Michael","first_name":"Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann"},{"last_name":"Marlow","first_name":"Frank","full_name":"Marlow, Frank"},{"last_name":"Brieler","first_name":"Felix","full_name":"Brieler, Felix"},{"full_name":"Lindén, Mika","first_name":"Mika","last_name":"Lindén"}],"year":"2006","title":"Early Stages of ZnS Growth Studied by Stopped-Flow UV Absorption Spectroscopy:  Effects of Educt Concentrations on the Nanoparticle Formation","quality_controlled":"1","citation":{"ama":"Tiemann M, Marlow F, Brieler F, Lindén M.

For the synthesis cetyltrimethylammonium bromide (CTABr) was used as a structure-directing agent; the resulting SnO2 powders were applied as films to commercially available sensor substrates by drop coating. Nitrogen physisorption shows specific surface areas up to 160 m2·g-1 and mean pore diameters of about 4 nm, as verified by TEM. The film conductance was measured in dependence on the CO concentration in humid synthetic air at a constant temperature of 300 °C. The sensors show a high sensitivity at low CO concentrations and turn out to be largely insensitive towards changes in the relative humidity. We compare the materials with commercially available SnO2-based sensors."}],"extern":"1","publication":"Sensors","user_id":"23547","_id":"25992","page":"318-323","status":"public","oa":"1","quality_controlled":"1","citation":{"ieee":"T.
