Compared to frequently investigated materials like tin dioxide (SnO2), tungsten trioxide (WO3), or gallium oxide (Ga2O3) indium oxide offers some unique properties. 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 material possesses enhanced pore-wall surface polarity as compared to that of mesoporous carbon prepared by the same technique without urea. This was verified by water sorption analysis.

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.","lang":"eng"}],"citation":{"apa":"Wagner, T., Kohl, C.-D., Malagù, C., Donato, N., Latino, M., Neri, G., &#38; Tiemann, M.

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.

Mesoporous SnO2 doped with palladium species was prepared and exposed to different gas mixtures at high temperature (600 °C) to simulate long term usage. After each exposure step a fraction of the sample was cooled down to “freeze” the current oxidation state of Pd which was then analyzed by X-ray Absorption Near-Edge Spectroscopy (XANES) using the 'white line' (i.e. the absorption peak corresponding to the transition from the 2p3/2 core level to unoccupied 4 d states) intensity of the L(III) edge as a probe for the oxidation state. The Pd oxidation state correlates with the response of the resistive SnO2 sensor to methane gas, as determined by measuring the gas response to different concentrations of methane. Samples treated with 5000 ppm methane in air show a significant reduction of Pd(II) to Pd(0), depending clearly on the carrier gas (synthetic air, pure nitrogen) and on the temperature (600 °C vs. 300 °C)."}],"quality_controlled":"1","date_created":"2021-10-09T04:59:31Z","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"type":"journal_article","author":[{"first_name":"T.","last_name":"Wagner","full_name":"Wagner, T."},{"last_name":"Bauer","first_name":"M.","full_name":"Bauer, M."},{"first_name":"T.","last_name":"Sauerwald","full_name":"Sauerwald, T."},{"full_name":"Kohl, C.-D.","first_name":"C.-D.","last_name":"Kohl"},{"orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael","full_name":"Tiemann, Michael","id":"23547"}],"publication_identifier":{"issn":["0040-6090"]},"status":"public","title":"X-ray absorption near-edge spectroscopy investigation of the oxidation state of Pd species in nanoporous SnO2 gas sensors for methane detection","year":"2011","article_type":"original","publication_status":"published","date_updated":"2023-03-09T08:28:16Z","language":[{"iso":"eng"}],"_id":"25962","page":"909-912","user_id":"23547","doi":"10.1016/j.tsf.2011.04.187"},{"article_type":"original","date_updated":"2023-03-09T08:30:11Z","publication_status":"published","publication_identifier":{"issn":["1424-8220"]},"author":[{"full_name":"Wagner, Thorsten","first_name":"Thorsten","last_name":"Wagner"},{"last_name":"Krotzky","first_name":"Sören","full_name":"Krotzky, Sören"},{"full_name":"Weiß, Alexander","last_name":"Weiß","first_name":"Alexander"},{"full_name":"Sauerwald, Tilman","first_name":"Tilman","last_name":"Sauerwald"},{"first_name":"Claus-Dieter","last_name":"Kohl","full_name":"Kohl, Claus-Dieter"},{"full_name":"Roggenbuck, Jan","first_name":"Jan","last_name":"Roggenbuck"},{"full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann","id":"23547"}],"title":"A High Temperature Capacitive Humidity Sensor Based on Mesoporous Silica","year":"2011","doi":"10.3390/s110303135","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/1424-8220/11/3/3135/pdf?version=1403314474"}],"abstract":[{"lang":"eng","text":"Capacitive sensors are the most commonly used devices for the detection of humidity because they are inexpensive and the detection mechanism is very specific for humidity. However, especially for industrial processes, there is a lack of dielectrics that are stable at high temperature (>200 °C) and under harsh conditions. We present a capacitive sensor based on mesoporous silica as the dielectric in a simple sensor design based on pressed silica pellets. Investigation of the structural stability of the porous silica under simulated operating conditions as well as the influence of the pellet production will be shown.

The product forms an approximately homogeneous monolayer of spheres on a sensor substrate and shows promising response to methane gas with low cross-sensitivity to water.
