The vapor sensors are tested using carbon disulfide, acetone, ethanol, and chloroform vapors. The CN<jats:sub><jats:italic>X<\/jats:italic><\/jats:sub>-MWNTs are produced by chemical vapor deposition process and then decorated with 14\u2009nm Ag nanoparticles (Ag-NPs). The samples are characterized using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. Our results demonstrate that Ag-decorated CN<jats:sub><jats:italic>X<\/jats:italic><\/jats:sub>-MWNTs exhibit a better response and sensitivity when compared with pristine CN<jats:sub><jats:italic>X<\/jats:italic><\/jats:sub>-MWNTs based sensors, making them promising candidates for air-pollutants environmental monitoring. The temperature effect on the sensor performance is also studied; we found that the detection mechanism could be tuned from physisorption, at room temperature, to chemisorption at higher working temperature. Finally, first-principles density functional calculations are carried out to understand the interactions between the systems involved in the sensors, finding good agreement between experimental results and the theoretical approach.<\/jats:p>","DOI":"10.1155\/2016\/4319498","type":"journal-article","created":{"date-parts":[[2016,1,13]],"date-time":"2016-01-13T21:04:29Z","timestamp":1452719069000},"page":"1-10","source":"Crossref","is-referenced-by-count":9,"title":["Temperature Dependence of Sensors Based on Silver-Decorated Nitrogen-Doped Multiwalled Carbon Nanotubes"],"prefix":"10.1155","volume":"2016","author":[{"given":"Eduardo","family":"Gracia-Espino","sequence":"first","affiliation":[{"name":"Department of Physics, Ume\u00e5 University, 90187 Ume\u00e5, Sweden"},{"name":"Department of Chemistry, Ume\u00e5 University, 90187 Ume\u00e5, Sweden"},{"name":"Advanced Materials Department, IPICYT, Camino a la Presa San Jos\u00e9 2055, Colonia Lomas 4a Secci\u00f3n, 78216 San Luis Potos\u00ed, SLP, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernab\u00e9","family":"Rebollo-Plata","sequence":"additional","affiliation":[{"name":"Advanced Materials Department, IPICYT, Camino a la Presa San Jos\u00e9 2055, Colonia Lomas 4a Secci\u00f3n, 78216 San Luis Potos\u00ed, SLP, Mexico"},{"name":"Instituto Tecnol\u00f3gico Superior de Irapuato, Carretera Irapuato-Silao Km. 12.5 Colonia El Copal, 36821 Irapuato, GTO, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugo","family":"Mart\u00ednez-Guti\u00e9rrez","sequence":"additional","affiliation":[{"name":"Centro de Nanociencias y Micro y Nanotecnolog\u00edas, Instituto Polit\u00e9cnico Nacional, Luis Enrique Erro S\/N, Colonia Zacatenco, 07738 Delegaci\u00f3n Gustavo A.
