The sensors were based on tin dioxide and prepared by means of thick film technology. The electrical and catalytic examinations showed that the abstraction of two hydrogen atoms from the organic molecule and formation of a water in result of reaction with a chemisorbed oxygen ion, determine the rate of oxidation reactions, and thus the sensor performance. The rate of the process depends on the order of carbon atoms and Lewis acidity of the molecule. Therefore, any modification of the surface centers of a sensor material, modifies not only the sensor sensitivity, but also its selectivity.<\/jats:p>","DOI":"10.3390\/s110404425","type":"journal-article","created":{"date-parts":[[2011,4,15]],"date-time":"2011-04-15T14:26:03Z","timestamp":1302877563000},"page":"4425-4437","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Oxidation of Hydrocarbons on the Surface of Tin Dioxide Chemical Sensors"],"prefix":"10.3390","volume":"11","author":[{"given":"Helena","family":"Teterycz","sequence":"first","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Technology, 50-372 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patryk","family":"Halek","sequence":"additional","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Technology, 50-372 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamil","family":"Wi\u015bniewski","sequence":"additional","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Technology, 50-372 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Grzegorz","family":"Halek","sequence":"additional","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Technology, 50-372 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Ko\u017alecki","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Wroc\u0142aw University of Technology, 50-373 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Izabela","family":"Polowczyk","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Wroc\u0142aw University of Technology, 50-373 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2011,4,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1016\/j.snb.2004.12.075","article-title":"Toward innovations of gas sensor technology","volume":"108","author":"Yamazoe","year":"2005","journal-title":"Sens.
