--- res: bibo_abstract: - We report on the synthesis and CO gas-sensing properties of mesoporous tin(IV) oxides (SnO2). 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.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Thorsten foaf_name: Wagner, Thorsten foaf_surname: Wagner - foaf_Person: foaf_givenName: Claus-Dieter foaf_name: Kohl, Claus-Dieter foaf_surname: Kohl - foaf_Person: foaf_givenName: Michael foaf_name: Fröba, Michael foaf_surname: Fröba - foaf_Person: foaf_givenName: Michael foaf_name: Tiemann, Michael foaf_surname: Tiemann foaf_workInfoHomepage: http://www.librecat.org/personId=23547 orcid: 0000-0003-1711-2722 bibo_doi: 10.3390/s6040318 dct_date: 2006^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/1424-8220 dct_language: eng dct_title: Gas Sensing Properties of Ordered Mesoporous SnO2@ ...
