Interestingly, various Pd nanostructures that have been realized by recent developments in nanotechnologies are known to show better performance than bulk Pd. This review highlights the characteristic properties, issues, and their possible solutions of hydrogen sensors based on the low-dimensional Pd nanostructures with more emphasis on Pd thin films and Pd nanowires. The finite size effects, relative strengths and weaknesses of the respective Pd nanostructures are discussed in terms of performance, manufacturability, and practical applicability.<\/jats:p>","DOI":"10.3390\/s110100825","type":"journal-article","created":{"date-parts":[[2011,1,13]],"date-time":"2011-01-13T12:17:23Z","timestamp":1294921043000},"page":"825-851","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":154,"title":["Low-Dimensional Palladium Nanostructures for Fast and Reliable Hydrogen Gas Detection"],"prefix":"10.3390","volume":"11","author":[{"given":"Jin-Seo","family":"Noh","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 120-749, Korea"}]},{"given":"Jun Min","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 120-749, Korea"}]},{"given":"Wooyoung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 120-749, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2011,1,13]]},"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":"377","DOI":"10.1016\/S0950-4230(99)00034-0","article-title":"Flammability of gas mixtures containing volatile organic compounds and hydrogen","volume":"13","author":"Liekhus","year":"2000","journal-title":"J.
