Thermal conversion of the metal nitrates into the respective metal oxides, and subsequent removal of the carbon matrix by thermal combustion, provides a versatile means to prepare mesoporous metal oxides (so-called nanocasting). This study aims to monitor the thermally induced processes by thermogravimetric analysis (TGA), coupled with mass ion detection (MS). The highly dispersed metal nitrates in the pores of the carbon matrix tend to react to the respective metal oxides at lower temperature than reported in the literature for pure, i.e., carbon-free, metal nitrates. The subsequent thermal combustion of the CMK-3 carbon matrix also occurs at lower temperature, which is explained by a catalytic effect of the metal oxides present in the pores. This catalytic effect is particularly strong for oxides of redox active metals, such as transition group VII and VIII metals (Mn, Fe, Co, Ni), Cu, and Ce.","lang":"eng"}],"type":"journal_article","publication":"Nanomaterials","language":[{"iso":"eng"}],"article_type":"original","user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"25939"},{"publication_status":"published","quality_controlled":"1","publication_identifier":{"issn":["0925-4005"]},"year":"2015","citation":{"chicago":"Klaus, Dominik, Danielle Klawinski, Sabrina Amrehn, Michael Tiemann, and Thorsten Wagner. “Light-Activated Resistive Ozone Sensing at Room Temperature Utilizing Nanoporous In2O3 Particles: Influence of Particle Size.” <i>Sensors and Actuators B: Chemical</i>, 2015, 181–85. <a href=\"https://doi.org/10.1016/j.snb.2014.09.021\">https://doi.org/10.1016/j.snb.2014.09.021</a>.","ieee":"D.

The most prominent one is its selectivity to oxidizing gases such as ozone (O3) or nitrogen dioxide (NO2) at low operating temperatures (<150°C). Combined with the photoreduction properties of nanocast, porous In2O3 highly selective sensing layers with a fast response can be prepared. In some cases even room temperature measurements are possible; therefore this material allows for designing low-power sensors without the need for special sensor substrates (e.g., μ-hotplates). Detailed analysis of the sensing mechanism reveals that known sensing models are not able to describe the observed effects.

The model aims at explaining (i) the drop in electronic resistance of n-type semiconducting In2O3 under UV light exposure, (ii) the light-enhanced reaction to oxidizing gases, and (iii) the faster reaction and regeneration in mesoporous In2O3 as compared to non-porous material. Contrary to the conventional double Schottky model the dominating factor for the change in resistance is a change of oxygen vacancy donor states (0.18 eV below the conduction band) in the bulk phase due to photoreduction, instead of chemisorption. For the faster reaction and regeneration we propose an explanation based on enhanced oxygen diffusion in the In2O3 crystal lattice, specifically dominant in the mesoporous structure. The response of ordered mesoporous In2O3 to NO2 is stronger than in case of unstructured bulk material (with an average grain size of ca. 40 nm). The reaction is significantly accelerated by illuminating the samples with UV light. However, the response of the mesoporous material is weaker in the illuminated case."}],"date_created":"2021-10-09T04:43:40Z","author":[{"last_name":"Wagner","full_name":"Wagner, Thorsten","first_name":"Thorsten"},{"first_name":"Claus-Dieter","full_name":"Kohl, Claus-Dieter","last_name":"Kohl"},{"first_name":"Cesare","last_name":"Malagù","full_name":"Malagù, Cesare"},{"first_name":"Nicola","last_name":"Donato","full_name":"Donato, Nicola"},{"full_name":"Latino, Mariangela","last_name":"Latino","first_name":"Mariangela"},{"first_name":"Giovanni","last_name":"Neri","full_name":"Neri, Giovanni"},{"full_name":"Tiemann, Michael","id":"23547","orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael"}],"date_updated":"2023-03-08T10:34:05Z","doi":"10.1016/j.snb.2013.02.025","title":"UV light-enhanced NO2 sensing by mesoporous In2O3: Interpretation of results by a new sensing model","publication_identifier":{"issn":["0925-4005"]},"quality_controlled":"1","publication_status":"published","page":"488-494","citation":{"short":"T.

Essential features of the model are photoreduction and a rate-limiting oxygen-diffusion step. Ordered, mesoporous In2O3 with a high specific surface area serves as a versatile system for experimental studies. Analytical techniques comprise conductivity measurements under a controlled atmosphere (synthetic air, pure N2) and temperature-resolved in-situ Fourier transform infrared (FTIR) spectroscopy. IR measurements reveal that oxygen vacancies form a donor level 0.18 eV below the conduction band.","lang":"eng"}],"department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547","_id":"25956","language":[{"iso":"eng"}],"article_type":"original"},{"language":[{"iso":"eng"}],"article_type":"original","user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"25957","status":"public","abstract":[{"text":"Poröse Funktionsmaterialien wie halbleitende Metalloxide, Kohlenstoff-Formen oder auch Silica werden aktuell von verschiedenen Wissenschaftsdisziplinen intensiv für Bereiche der Energiespeicherung, Sensorik, Katalyse und Stofftrennung erforscht.
