The sensor was based on a galvanic cell O2, SO2, Au, Li2SO4-V2O5|Li3PO4-Li2SiO3|Au, SO2, O2. The Li3PO4-Li2SiO3 thin film was deposited on the Al2O3 substrate by RF magnetron sputtering, and the Au patterns were fabricated as the electrodes. The sensing electrode materials of Li2SO4-V2O5 with different dopants TiO2 and MgO were prepared, and as the ratio of Li2SO4:TiO2 is 1:1 (mol) with 5 wt. % V2O5 and 5 wt. % MgO, the sensor showed relatively good response characteristics to SO2 at 450 \u00b0C. Then, the sensor was further tested at the working temperature from 400 \u00b0C to 500 \u00b0C. The results show that the sensor has good response to SO2 at 400\u2013450 \u00b0C, and the sensitivity is 90.15\u201357.19 mV\/dec. The response and recovery times are 20\u201340 s and 2.5\u20134 min, respectively, when the gas concentration of SO2 increases from 10 ppm to 100 ppm and then decreases to 10 ppm. At 425 \u00b0C, the sensitivity is close to the theoretical values, and the final recovery potential of the sensor is almost consistent with the initial potential.<\/jats:p>","DOI":"10.1063\/1.5080474","type":"journal-article","created":{"date-parts":[[2019,6,3]],"date-time":"2019-06-03T12:58:47Z","timestamp":1559566727000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":15,"title":["A potentiometric SO2 gas sensor based on the Li3PO4-Li2SiO3 solid electrolyte thin film"],"prefix":"10.1063","volume":"90","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9688-4693","authenticated-orcid":false,"given":"Kedong","family":"Chen","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Xi\u2019an Jiaotong University 1 , Xi\u2019an, Shaanxi 710049, People\u2019s Republic of China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University 2 , No. 99, Yanxiang Road, Xi\u2019an, Shaanxi 710054, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Xi\u2019an Jiaotong University 1 , Xi\u2019an, Shaanxi 710049, People\u2019s Republic of China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University 2 , No. 99, Yanxiang Road, Xi\u2019an, Shaanxi 710054, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9558-981X","authenticated-orcid":false,"given":"Hairong","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Xi\u2019an Jiaotong University 1 , Xi\u2019an, Shaanxi 710049, People\u2019s Republic of China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University 2 , No. 99, Yanxiang Road, Xi\u2019an, Shaanxi 710054, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanqing","family":"Gu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Xi\u2019an Jiaotong University 1 , Xi\u2019an, Shaanxi 710049, People\u2019s Republic of China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University 2 , No. 99, Yanxiang Road, Xi\u2019an, Shaanxi 710054, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2019,6,3]]},"reference":[{"key":"2023070415221769800_c1","doi-asserted-by":"publisher","first-page":"261","DOI":"10.1007\/s11581-008-0300-6","volume":"15","year":"2009","journal-title":"Ionics"},{"key":"2023070415221769800_c2","doi-asserted-by":"publisher","first-page":"B610","DOI":"10.1149\/2.0291711jes","volume":"164","year":"2017","journal-title":"J.
