Single atom catalysts (SACs), possessed with highly consistent single active sites, have great potentials for overcoming such issues. Herein, the authors used SACs to modulate kinetic process of gas sensitive reaction. The supported Pd SACs, established by a metal organic frameworks\u2010templated approach, promoted greatly the detection capacity to hydrogen sulfide (H\n                    <jats:sub>2<\/jats:sub>\n                    S) gas with a very high sensitivity and selectivity. Density functional theory calculations show that the supported Pd SACs not only increased the number of electrons transferring from H\n                    <jats:sub>2<\/jats:sub>\n                    S molecules to Pd SACs, but strengthened surface affinity to H\n                    <jats:sub>2<\/jats:sub>\n                    S. Moreover, the H\uf8ffS bonds of H\n                    <jats:sub>2<\/jats:sub>\n                    S molecules absorbed on Pd atomic sites are more likely to be dehydrogenated directly into sulfur species. Significantly, quasi in situ XPS analysis confirmed the presence of sulfur species during H\n                    <jats:sub>2<\/jats:sub>\n                    S detection process, which may be a major cause for such detection signal. Based on these results, a suitable sensing principle for H\n                    <jats:sub>2<\/jats:sub>\n                    S gas driven by Pd SACs was put forward. This work will enrich catalytic electronics in chemiresistive gas sensing.\n                  <\/jats:p>","DOI":"10.1002\/smll.202105643","type":"journal-article","created":{"date-parts":[[2021,10,30]],"date-time":"2021-10-30T01:10:05Z","timestamp":1635556205000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["The Dehydrogenation of H\u2010S Bond into Sulfur Species on Supported Pd Single Atoms Allows Highly Selective and Sensitive Hydrogen Sulfide Detection"],"prefix":"10.1002","volume":"17","author":[{"given":"Bo","family":"Liu","sequence":"first","affiliation":[{"name":"Wuhan National Laboratory for Optoelectronics School of Optical and Electronic Information Huazhong University of Science and Technology  Wuhan 430074 P.
