However, its applicability is unsure for the single-atom-anchored two-dimensional (2D) catalysts. Here, taking the hydrogen (H) adsorption on the single-atom-anchored 2D basal plane as example, we examine the influence of orbitals interaction on the bond strength of hydrogen adsorption. We find that the adsorption of H is formed mainly via the hybridization between the 1s orbital of H and the vertical d\n                    <jats:sub>z2<\/jats:sub>\n                    orbital of anchored atoms. The other four projected d orbitals (d\n                    <jats:sub>xy<\/jats:sub>\n                    \/d\n                    <jats:sub>x2\u2212y2<\/jats:sub>\n                    , d\n                    <jats:sub>xz<\/jats:sub>\n                    \/d\n                    <jats:sub>yz<\/jats:sub>\n                    ) have no contribution to the H chemical bond. There is an explicit linear relation between the d\n                    <jats:sub>z2<\/jats:sub>\n                    -band center and the H bond strength. The d\n                    <jats:sub>z2<\/jats:sub>\n                    -band center is proposed as an activity descriptor for hydrogen evolution reaction (HER). We demonstrate that the d\n                    <jats:sub>z2<\/jats:sub>\n                    -band center is valid for the single-atom active sites on a single facet, such as the basal plane of 2D nanosheets. For the surface with multiple facets, such as the surface of three-dimensional (3D) polyhedral nanoparticles, the d-band center is more suitable.\n                  <\/jats:p>","DOI":"10.1088\/1361-648x\/abe9da","type":"journal-article","created":{"date-parts":[[2021,2,25]],"date-time":"2021-02-25T17:30:36Z","timestamp":1614274236000},"page":"245201","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["Vertical-orbital band center as an activity descriptor for hydrogen evolution reaction on single-atom-anchored 2D catalysts"],"prefix":"10.1088","volume":"33","author":[{"given":"Wen","family":"Qiao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8501-4230","authenticated-orcid":false,"given":"Shiming","family":"Yan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deyou","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyong","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9108-9930","authenticated-orcid":false,"given":"Wenbo","family":"Mi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dunhui","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2021,5,13]]},"reference":[{"key":"cmabe9dabib1","doi-asserted-by":"publisher","first-page":"49","DOI":"10.1016\/j.nanoen.2017.08.021","type":"journal-article","article-title":"Hydrogen generation by water splitting using MoS2 and other transition metal dichalcogenides","volume":"41","author":"Gupta","year":"2017","journal-title":"Nano Energy"},{"key":"cmabe9dabib2","doi-asserted-by":"publisher","first-page":"1917","DOI":"10.1002\/adma.201503270","type":"journal-article","article-title":"2D transition-metal-dichalcogenide-nanosheet-based composites for photocatalytic and electrocatalytic hydrogen evolution reactions","volume":"28","author":"Lu","year":"2016","journal-title":"Adv.
