Numerous parameters determine catalytic activity and selectivity towards the most desired hydrocarbons. The performances of cobalt\u2010based catalysts used in the reaction are known to depend critically on Co particle size and crystallographic phase. Here, we present a comparative study of Co\u2010based catalysts supported on three carbon supports: multi\u2010wall carbon nanotubes, carbon nanofibers and a fibrous material. Our results show that, while the selectivity towards C5+ follows the expected tendency with respect to Co particle size, this is not the case for the TOF. These results can be rationalized considering that the amount of H<jats:sub>2<\/jats:sub> uptake on each catalyst increases with oxygen and defect concentration on the support. The catalyst on the support presenting many edges and oxygen surface groups, necessary for H<jats:sub>2<\/jats:sub> spillover, presents the highest activity. Furthermore, the hydrogen spillover contributes to the enhancement of olefin hydrogenation and methane production.<\/jats:p>","DOI":"10.1002\/cctc.201901934","type":"journal-article","created":{"date-parts":[[2019,11,27]],"date-time":"2019-11-27T12:10:07Z","timestamp":1574856607000},"page":"1117-1128","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Hydrogen Spillover in the Fischer\u2010Tropsch Synthesis on Carbon\u2010supported Cobalt Catalysts"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2928-5276","authenticated-orcid":false,"given":"Amel C.","family":"Ghogia","sequence":"first","affiliation":[{"name":"Universit\u00e9 de Toulouse, IMT Mines Albi, UMR CNRS 5302  Centre RAPSODEE Campus Jarlard 81013 Albi cedex 09 France"},{"name":"LPCNO Universit\u00e9 de Toulouse, CNRS, INSA, UPS  135 avenue de Rangueil 31077 Toulouse France"},{"name":"LCC, CNRS-UPR 8241, ENSIACET Universit\u00e9 de Toulouse  France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6314-7662","authenticated-orcid":false,"given":"Simon","family":"Cayez","sequence":"additional","affiliation":[{"name":"LPCNO Universit\u00e9 de Toulouse, CNRS, INSA, UPS  135 avenue de Rangueil 31077 Toulouse France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3183-7519","authenticated-orcid":false,"given":"Bruno F.","family":"Machado","sequence":"additional","affiliation":[{"name":"Laboratory of Separation and Reaction Engineering \u2013 Laboratory of Catalysis and Materials (LSRE-LCM) Chemical Engineering Department, Faculty of Engineering University of Porto  Rua Dr. Roberto Frias s\/n 4200-465 Porto Portugal"}]},{"given":"Ange","family":"Nzihou","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Toulouse, IMT Mines Albi, UMR CNRS 5302  Centre RAPSODEE Campus Jarlard 81013 Albi cedex 09 France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1424-2724","authenticated-orcid":false,"given":"Philippe","family":"Serp","sequence":"additional","affiliation":[{"name":"LCC, CNRS-UPR 8241, ENSIACET Universit\u00e9 de Toulouse  France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3033-1620","authenticated-orcid":false,"given":"Katerina","family":"Soulantica","sequence":"additional","affiliation":[{"name":"LPCNO Universit\u00e9 de Toulouse, CNRS, INSA, UPS  135 avenue de Rangueil 31077 Toulouse France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7770-1487","authenticated-orcid":false,"given":"Doan","family":"Pham Minh","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Toulouse, IMT Mines Albi, UMR CNRS 5302  Centre RAPSODEE Campus Jarlard 81013 Albi cedex 09 France"}]}],"member":"311","published-online":{"date-parts":[[2019,12,27]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.techfore.2005.06.012"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fuproc.2009.07.007"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/ie0712434"},{"key":"e_1_2_7_4_1","unstructured":"\u00a0"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/acscatal.5b00057"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.iecr.8b03850"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9517(84)90110-6"},{"key":"e_1_2_7_8_1","unstructured":"\u00a0"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0920-5861(00)00265-0"},{"key":"e_1_2_7_10_2","first-page":"4","volume":"24","author":"Tavasoli A.","year":"2005","journal-title":"Iran.
