This technique is used for monitoring hydrogen uptake and release from different carbon electrocatalysts: 3D-graphene, single-walled carbon nanotube networks, multi-walled carbon nanotube networks, and carbon nanotube thread. It allows an accurate determination of the hydrogen mass absorbed in electrodes made from these materials, with significant enhancement in the signal-to-noise ratio for trace hydrogen avoiding recourse to ultra-high vacuum procedures. The hydrogen mass spectra account for the enhanced surface capability for hydrogen adsorption in the different types of electrode in similar uptake conditions, and confirm their enhanced hydrogen storage capacity, pointing to a great potential of carbon nanotube threads in replacing the heavier metals or metal alloys as hydrogen storage media.<\/jats:p>","DOI":"10.3390\/nano11051079","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T13:59:14Z","timestamp":1619099954000},"page":"1079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Hydrogen Nanometrology in Advanced Carbon Nanomaterial Electrodes"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8647-4842","authenticated-orcid":false,"given":"Rui","family":"Lobo","sequence":"first","affiliation":[{"name":"Laboratory of Nanophysics\/Nanotechnology and Energy (N2E), Center of Technology and Systems (CTS-UNINOVA), NOVA School of Science &amp; Technology, FCT-NOVA, Universidade NOVA de Lisboa, 2829-516 Caparica, Portugal"},{"name":"Department of Physics, NOVA School of Science &amp; Technology, FCT-NOVA, Universidade NOVA de Lisboa, 2829-516 Caparica, Portugal"}]},{"given":"Noe","family":"Alvarez","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Cincinnati, Cincinnati, OH 45221, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0041-7821","authenticated-orcid":false,"given":"Vesselin","family":"Shanov","sequence":"additional","affiliation":[{"name":"Department of Chemical and Environmental Engineering, University of Cincinnati, Cincinnati, OH 45221, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8229","DOI":"10.1021\/acs.est.7b01466","article-title":"Environmental Applications of 2D Molybdenum Disulfide (MoS2) Nanosheets","volume":"51","author":"Wang","year":"2017","journal-title":"Environ.
