Herein, using oxalic acid (OA), citric acid (CA) and tartaric acid (TA) as auxiliary agents, three homogeneous tungsten oxide nanosheets were prepared by the rapid microwave-assisted hydrothermal method. The potential exhaled gases of various diseases were screened for the gas sensitivity test. Compared with WO3-OA and WO3-TA, WO3-CA exhibits significant sensitivity to formaldehyde, acetone and various alkanes. Photoluminescence (PL) chromatography and photoelectric properties show that its excellent gas sensitivity is due to its abundant oxygen vacancies and high surface charge migration rate, which can provide more preferential reaction sites with gas molecules. The experiment is of great significance for the sensor selection of the large disease exhaled gas sensor array.<\/jats:p>","DOI":"10.3390\/nano12183211","type":"journal-article","created":{"date-parts":[[2022,9,16]],"date-time":"2022-09-16T01:35:10Z","timestamp":1663292110000},"page":"3211","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Microwave Synthesized 2D WO3 Nanosheets for VOCs Gas Sensors"],"prefix":"10.3390","volume":"12","author":[{"given":"He","family":"Liu","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingyao","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kedong","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Chen","sequence":"additional","affiliation":[{"name":"Shanghai Yaolu Instrument & Equipment Co., Ltd., Shanghai 200444, China"},{"name":"NEST Lab, Department of Physics, Department of Chemistry, College of Sciences, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunling","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaoxin","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4214-8532","authenticated-orcid":false,"given":"Jiaqiang","family":"Xu","sequence":"additional","affiliation":[{"name":"NEST Lab, Department of Physics, Department of Chemistry, College of Sciences, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenyu","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"859","DOI":"10.1016\/j.buildenv.2008.06.007","article-title":"On-site passive flux sampler measurement of emission rates of carbonyls and VOCs from multiple indoor sources","volume":"44","author":"Shinohara","year":"2009","journal-title":"Build.
