Pd NPs were deposited on organic nanofiber materials by DC magnetron sputtering. The temperature dependence of the sensitivity at 25 ppm H2 was characterized and discussed, and the maximum response of the sensor increased linearly with increasing measurement temperature. Performances of the hydrogen sensor were investigated with hydrogen concentration ranging from 5 ppm to 50 ppm. This sensor exhibits high sensitivity, with the response up to 6.55% for H2 as low as 5 ppm, and the output response of the hydrogen sensor increased linearly with the square root of hydrogen concentration. A cycling test between pure nitrogen and 25 ppm hydrogen concentration was performed, and the hydrogen sensor exhibited excellent consistency.<\/jats:p>","DOI":"10.3390\/s19061290","type":"journal-article","created":{"date-parts":[[2019,3,15]],"date-time":"2019-03-15T04:12:09Z","timestamp":1552623129000},"page":"1290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Flexible and Highly Sensitive Hydrogen Sensor Based on Organic Nanofibers Decorated by Pd Nanoparticles"],"prefix":"10.3390","volume":"19","author":[{"given":"Hongchuan","family":"Jiang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yibing","family":"Yu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luying","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Zhu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0907-9531","authenticated-orcid":false,"given":"Xiaohui","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wanli","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1901","DOI":"10.1126\/science.1109157","article-title":"Cleaning the air and improving health with hydrogen fuel-cell vehicles","volume":"308","author":"Jacobson","year":"2005","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"353","DOI":"10.1038\/35104634","article-title":"Hydrogen-storage materials for mobile applications","volume":"414","author":"Schlapbach","year":"2001","journal-title":"Nature"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"7443","DOI":"10.1021\/nn2023717","article-title":"Networks of ultrasmall Pd\/Cr nanowires as high performance hydrogen sensors","volume":"5","author":"Zeng","year":"2011","journal-title":"ACS Nano"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"382","DOI":"10.1039\/b9nr00015a","article-title":"Nanostructured Pt decorated graphene and multi walled carbon nanotube based room temperature hydrogen gas sensor","volume":"1","author":"Kaniyoor","year":"2009","journal-title":"Nanoscale"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"1402","DOI":"10.1021\/cr800339k","article-title":"Review of electrochemical hydrogen sensors","volume":"109","author":"Korotcenkov","year":"2009","journal-title":"Chem.
