This paper applied the Au-doped TiO2 nanotube array sensor (Au-TiO2 NTAs) to detect SF6 decomposed components. The electrochemical constant potential method was adopted in the Au-TiO2 NTAs\u2019 fabrication, and a series of experiments were conducted to test the characteristic SF6 decomposed gases for a thorough investigation of sensing performances. The sensing characteristic curves of intrinsic and Au-doped TiO2 NTAs were compared to study the mechanism of the gas sensing response. The results indicated that the doped Au could change the TiO2 nanotube arrays\u2019 performances of gas sensing selectivity in SF6 decomposed components, as well as reducing the working temperature of TiO2 NTAs.<\/jats:p>","DOI":"10.3390\/s141019517","type":"journal-article","created":{"date-parts":[[2014,10,17]],"date-time":"2014-10-17T10:27:19Z","timestamp":1413541639000},"page":"19517-19532","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Gas Sensitivity and Sensing Mechanism Studies on  Au-Doped TiO2 Nanotube Arrays for Detecting SF6 Decomposed Components"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5872-2039","authenticated-orcid":false,"given":"Xiaoxing","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]},{"given":"Lei","family":"Yu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]},{"given":"Jing","family":"Tie","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]},{"given":"Xingchen","family":"Dong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]}],"member":"1968","published-online":{"date-parts":[[2014,10,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"864","DOI":"10.1109\/TDEI.2013.6518956","article-title":"Correlation analysis between formation process of SF6 decomposed components and partial discharge qualities","volume":"20","author":"Ju","year":"2013","journal-title":"IEEE Trans.
