Unassisted and  acetone-assisted thermal synthesis methods are used to synthesis SnO2 nanomaterials. The prepared SnO2 nanomaterials have been characterized by X-ray powder diffraction, scanning electron microscopy and N2 adsorption\u2212desorption. Four types of SnO2 films were obtained by mixing pure deionized water and liquid acetone with the two types of  as-prepared powders, respectively. The acetone gas sensing properties of sensors coated by these films were evaluated. Testing results reveal that the sensor coated by the film fabricated by mixing liquid acetone with the SnO2 nanomaterial synthesized by the acetone-assisted thermal method exhibits the best acetone gas sensing performance. The sensor is optimized for the smooth adsorption and desorption of acetone gas thanks to the participation of acetone both in the procedure of synthesis of the SnO2 nanomaterial and the device fabrication, which results in a distinct response\u2013recovery behavior.<\/jats:p>","DOI":"10.3390\/s150100352","type":"journal-article","created":{"date-parts":[[2014,12,26]],"date-time":"2014-12-26T05:52:39Z","timestamp":1419573159000},"page":"352-364","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Fabrication of a SnO2-Based Acetone Gas Sensor Enhanced by Molecular Imprinting"],"prefix":"10.3390","volume":"15","author":[{"given":"Wenhu","family":"Tan","sequence":"first","affiliation":[]},{"given":"Xiaofan","family":"Ruan","sequence":"additional","affiliation":[]},{"given":"Qiuxiang","family":"Yu","sequence":"additional","affiliation":[]},{"given":"Zetai","family":"Yu","sequence":"additional","affiliation":[]},{"given":"Xintang","family":"Huang","sequence":"additional","affiliation":[]}],"member":"1968","published-online":{"date-parts":[[2014,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1016\/j.snb.2006.09.047","article-title":"Metal oxide-based gas sensor research: How to?","volume":"121","author":"Barsan","year":"2007","journal-title":"Sens.
