The graphite-on-paper (GOP) substrate offers advantages such as good thermo-electrical conductivity, low cost, and uncomplicated preparation technology. Quasi-1-dimensional palladium (Pd) thin films with 8 nm and 60 nm thicknesses were deposited on the GOP substrates using the vacuum evaporation technique. Thanks to the unique properties of the GOP substrate, a continuous Pd microfiber network structure appeared after deposition of the ultra-thin Pd film. Additionally, the sensing performance of the palladium-based hydrogen sensor was not affected, whether using GOP or paper substrate at 25 \u00b0C. Surprisingly, heating-induced loss of sensitivity was restrained due to the increased electrical conductivity of the GOP substrate at 50 \u00b0C.<\/jats:p>","DOI":"10.3390\/s22103926","type":"journal-article","created":{"date-parts":[[2022,5,22]],"date-time":"2022-05-22T07:13:57Z","timestamp":1653203637000},"page":"3926","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Low-Dimensional Palladium on Graphite-on-Paper Substrate for Hydrogen Sensing"],"prefix":"10.3390","volume":"22","author":[{"given":"Boyi","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mechanical and Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7172-141X","authenticated-orcid":false,"given":"Takeshi","family":"Hashishin","sequence":"additional","affiliation":[{"name":"Faculty of Advanced Science & Technology, Kumamoto University, 2-39-1 Kurokami, Kumamoto 860-8555, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6348-0879","authenticated-orcid":false,"given":"Dzung Viet","family":"Dao","sequence":"additional","affiliation":[{"name":"Queensland Micro- and Nanotechnology Centre, Griffith University, Nathan, QLD 4111, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6701-5694","authenticated-orcid":false,"given":"Yong","family":"Zhu","sequence":"additional","affiliation":[{"name":"Queensland Micro- and Nanotechnology Centre, Griffith University, Nathan, QLD 4111, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,22]]},"reference":[{"key":"ref_1","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_2","doi-asserted-by":"crossref","first-page":"447","DOI":"10.1016\/j.ijhydene.2004.10.024","article-title":"Observer designs for fuel processing reactors in fuel cell power systems","volume":"30","author":"Arcak","year":"2005","journal-title":"Int.
