However, the catalytic nature of different cobalt species is ambiguous, and the development of active and selective Co\u2010based CO\n 2<\/jats:sub>\n \u2010ODP catalysts are at the very early stage. In this study, Co species on CoO\n x<\/jats:sub>\n \/Silicalite\u20101 catalysts are regulated by calcining the catalyst precursor at 500\u00b0C under Ar, Air, and H\n 2<\/jats:sub>\n atmospheres, respectively. Characterization results reveal that the proportion of Co\n 3<\/jats:sub>\n O\n 4<\/jats:sub>\n spinel, metallic Co, and tetrahedrally coordinated Co\n 2+<\/jats:sup>\n species (Td\u2010Co\n 2+<\/jats:sup>\n ) is easily altered by changing the calcining atmosphere. Moreover, Td\u2010Co\n 2+<\/jats:sup>\n is revealed to be the active site for CO\n 2<\/jats:sub>\n \u2010ODP while Co\n 0<\/jats:sup>\n is active for side reactions such as cracking and reforming. As a result of the richest Td\u2010Co\n 2+<\/jats:sup>\n and diminished Co\n 0<\/jats:sup>\n over the CoO\n x<\/jats:sub>\n \/Silicalite\u20101 catalyst calcined in Ar, the highest CO\n 2<\/jats:sub>\n \u2010ODP performance is achieved with a propylene space\u2010time yield of 15.88 mmol\u00b7g\n cat<\/jats:sub>\n \u22121<\/jats:sup>\n \u00b7h\n \u22121<\/jats:sup>\n . Besides acting as a mild oxidant, the additional functions of CO\n 2<\/jats:sub>\n are to retard the reduction of Td\u2010Co\n 2+<\/jats:sup>\n and to reduce the coke accumulation via the reverse Boudouard reaction during CO\n 2<\/jats:sub>\n \u2010ODP. These understandings are important guides for optimizing with more efficient Co\u2010based CO\n 2<\/jats:sub>\n \u2010ODP catalyst.\n <\/jats:p>","DOI":"10.1002\/chem.71210","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T04:15:03Z","timestamp":1780632903000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CoO\n x<\/sub>\n \/Silicalite\u20101 Tailored by Calcining Atmosphere for Oxidative Dehydrogenation of Propane With CO\n 2<\/sub>"],"prefix":"10.1002","volume":"32","author":[{"given":"Jian\u2010Kang","family":"Liao","sequence":"first","affiliation":[{"name":"Key Laboratory of Syngas Conversion of Shaanxi Province School of Chemistry & Chemical Engineering Shaanxi Normal University Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiang","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Syngas Conversion of Shaanxi Province School of Chemistry & Chemical Engineering Shaanxi Normal University Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Peng","sequence":"additional","affiliation":[{"name":"Key Laboratory of Syngas Conversion of Shaanxi Province School of Chemistry & Chemical Engineering Shaanxi Normal University Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han\u2010Qing","family":"Ge","sequence":"additional","affiliation":[{"name":"Key Laboratory of Syngas Conversion of Shaanxi Province School of Chemistry & Chemical Engineering Shaanxi Normal University Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4458-4998","authenticated-orcid":false,"given":"Zhong\u2010Wen","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Syngas Conversion of Shaanxi Province School of Chemistry & Chemical Engineering Shaanxi Normal University Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,4]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"14250","article-title":"Boosting Propane Dehydrogenation by the Regioselective Distribution of Subnanometric CoO Clusters in MFI Zeolite Nanosheets","volume":"15","author":"Lv X.
