The resulting heterostructures consisted of \u03b1-Fe2O3 rod templates and ZnO branched crystals with an average diameter of approximately 12 nm and length of 25 nm. The gas-sensing results demonstrated that the \u03b1-Fe2O3\u2013ZnO heterostructure-based sensor exhibited excellent sensitivity, selectivity, and stability toward low-concentration NO2 gas at an optimal temperature of 300 \u00b0C. The \u03b1-Fe2O3\u2013ZnO sensor, in particular, demonstrated substantially higher sensitivity compared with pristine \u03b1-Fe2O3, along with faster response and recovery speeds under similar test conditions. An appropriate material synergic effect accounts for the considerable enhancement in the NO2 gas-sensing performance of the \u03b1-Fe2O3\u2013ZnO heterostructures.<\/jats:p>","DOI":"10.3390\/ijms22136884","type":"journal-article","created":{"date-parts":[[2021,6,27]],"date-time":"2021-06-27T22:24:57Z","timestamp":1624832697000},"page":"6884","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Enhanced Sensing Ability of Brush-Like Fe2O3-ZnO Nanostructures towards NO2 Gas via Manipulating Material Synergistic Effect"],"prefix":"10.3390","volume":"22","author":[{"given":"Yuan-Chang","family":"Liang","sequence":"first","affiliation":[{"name":"Department of Optoelectronics and Materials Technology, National Taiwan Ocean University, Keelung 20224, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Wei","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Optoelectronics and Materials Technology, National Taiwan Ocean University, Keelung 20224, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2229","DOI":"10.1039\/c2ce06400f","article-title":"Template-free synthesis of monodisperse \u03b1-Fe2O3 porous ellipsoids and their application to gas sensors","volume":"14","author":"Sun","year":"2012","journal-title":"CrystEngComm"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"7948","DOI":"10.1039\/C5CE01519G","article-title":"Crystal growth and shell layer crystal feature-dependent sensing and photoactivity performance of zinc oxide\u2013indium oxide core\u2013shell nanorod heterostructures","volume":"17","author":"Liang","year":"2015","journal-title":"CrystEngComm"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"16272","DOI":"10.1021\/acsomega.0c02107","article-title":"Design of Hydrothermally Derived Fe2O3 Rods with Enhanced Dual Functionality via Sputtering Decoration of a Thin ZnO Coverage Layer","volume":"5","author":"Liang","year":"2020","journal-title":"ACS Omega"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"669","DOI":"10.3390\/nano9050669","article-title":"Improvement of Ethanol Gas-Sensing Responses of ZnO\u2013WO3 Composite Nanorods through Annealing Induced Local Phase Transformation","volume":"9","author":"Liang","year":"2019","journal-title":"Nanomaterials"},{"key":"ref_5","doi-asserted-by":"crossref","unstructured":"Rackauskas, S., Barbero, N., Barolo, C., and Viscardi, G.
