The reductive properties and catalytic behaviour in methanol decomposition of the materials are also studied. Depending on the chemical nature of the support, the predominant formation of: isolated iron species, strongly interacting with the support (for SBA-15), mixture of hematite and binary MgFe2O4 nanoparticles (for MgO) or almost homogeneously dispersed hematite particles (for CeO2) are observed. The state of iron species strongly affects their catalytic properties.

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","type":"journal_article"},{"language":[{"iso":"eng"}],"publication":"Sensors","abstract":[{"lang":"eng","text":"We report on the synthesis and CO gas-sensing properties of mesoporous tin(IV) oxides (SnO2).

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.

Mesoporous SBA-15 silica and CMK-3 carbon were successively used as hard structure matrixes. The carbon pore system was infiltrated with Mg(NO3)2, which was then converted to MgO at 573 K; the carbon matrix was finally removed by thermal combustion. The structure of the mesoporous MgO corresponds to that of the original SBA-15 silica. The products consist of hexagonally arranged cylindrical mesopores and crystalline pore walls. The efficiency of the replication series was studied by variation of the infiltration method and comprehensive pore size analysis of all involved mesoporous materials. The in situ formation of MgO inside the CMK-3 carbon pore system was monitored by thermal analysis. Postsynthetic treatment of the products at 823 K in a vacuum prior to removal of the carbon matrix was found to improve the crystallinity but to diminish the periodic order of the pore system.","lang":"eng"}],"type":"journal_article","publication":"Chemistry of Materials","language":[{"iso":"eng"}],"extern":"1","article_type":"original","user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"25991","citation":{"ama":"Roggenbuck J, Koch G, Tiemann M.

Benzene is used a an additive which acts as a weak swelling agent although most of the benzene molecules are found to reside near the surfactant/silicate interface region rather than in the micelle cores. With increasing relative amounts of benzene, the curvature of the micellar aggregates decreases, which finally leads to a transition from (hexagonally) rodlike to lamellar; a mechanism for this change in curvature is suggested."}],"user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"25998","language":[{"iso":"eng"}],"extern":"1","article_type":"original"},{"abstract":[{"text":"Mesoporous aluminophosphates with a strict ratio of Al∶P = 1∶1 have been synthesised from a single-source molecular precursor.","lang":"eng"}],"status":"public","publication":"Chemical Communications","type":"journal_article","article_type":"original","language":[{"iso":"eng"}],"extern":"1","_id":"26001","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547","year":"2002","page":"406-407","citation":{"bibtex":"@article{Tiemann_Fröba_2002, title={Mesoporous aluminophosphates from a single-source precursor}, DOI={<a href=\"https://doi.org/10.1039/b110662g\">10.1039/b110662g</a>}, journal={Chemical Communications}, author={Tiemann, Michael and Fröba, Michael}, year={2002}, pages={406–407} }","short":"M.
