The physical and chemical properties of In2O3\/SnO2 hetero-nanofibers were characterized and analyzed by X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), Energy Dispersive X-Ray Spectroscopy (EDX), specific surface Brunauer\u2013Emmett\u2013Teller (BET) and X-ray photoelectron spectroscopy (XPS). Gas sensing properties of In2O3\/SnO2 composite hetero-nanofibers were measured with six kinds of indoor volatile organic gases in concentration range of 0.5~50 ppm at the operating temperature of 275 \u00b0C. The In2O3\/SnO2 composite hetero-nanofibers sensor exhibited good formaldehyde sensing properties, which would be attributed to the formation of n-n homotype heterojunction in the In2O3\/SnO2 composite hetero-nanofibers. Finally, the sensing mechanism of the In2O3\/SnO2 composite hetero-nanofibers was analyzed based on the energy-band principle.<\/jats:p>","DOI":"10.3390\/s17081822","type":"journal-article","created":{"date-parts":[[2017,8,9]],"date-time":"2017-08-09T05:10:01Z","timestamp":1502255401000},"page":"1822","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Electrospinning Hetero-Nanofibers In2O3\/SnO2 of Homotype Heterojunction with High Gas Sensing Activity"],"prefix":"10.3390","volume":"17","author":[{"given":"Haiying","family":"Du","sequence":"first","affiliation":[{"name":"College of mechanical and Electronic Engineering, Dalian Minzu University, Dalian 116600, China"},{"name":"School of Electronic Science and Technology, Dalian University of Technology, Dalian 116023, China"},{"name":"Department of Electrical and Computer Engineering, College of Engineering, Iowa State University, Ames, IA 50011, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PengJun","family":"Yao","sequence":"additional","affiliation":[{"name":"School of Educational Technology, Shenyang Normal University, Shenyang 110034, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5654-403X","authenticated-orcid":false,"given":"Yanhui","family":"Sun","sequence":"additional","affiliation":[{"name":"College of mechanical and Electronic Engineering, Dalian Minzu University, Dalian 116600, China"},{"name":"School of Electronic Science and Technology, Dalian University of Technology, Dalian 116023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electronic Science and Technology, Dalian University of Technology, Dalian 116023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huisheng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electronic Science and Technology, Dalian University of Technology, Dalian 116023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naisen","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Physics and Materials Engineering, Dalian Minzu University, Dalian 116600, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"462","DOI":"10.1016\/j.jscs.2015.04.003","article-title":"Metal oxides as photocatalysts","volume":"19","author":"Khan","year":"2015","journal-title":"J.
