For the catalyst consisting of Ni and Ba, the variation of Ba loading while keeping Ni loading constant was studied. The promotion in terms of enhanced CH4 yield was found only for the addition of barium to 15 wt% Ni/Al2O3. In contrast, K and Na addition increased the selectivity to CO while decreasing conversion. For the Ru-based catalyst series, no enhancement in conversion or CH4 yield was attained by any of the alkaline metals. CO2 temperature-programed desorption (CO2-TPD) revealed that the amount of chemisorbed CO2 increased significantly after the addition of the base metal. The reactivity of COx ad-species for each catalyst was assessed by temperature-programed surface reaction (TPSR). The characterization revealed that the performance in the Sabatier reaction was a result of the interplay between the amount of chemisorbed CO2 and the reactivity of the COx ad-species, which was maximized for the (10%Ba)15%Ni/Al2O3 catalyst.The Financial support from the Spanish Ministry MINECO (projects PID2020- 119160RB-C21 and -C22), Gobierno de Aragón (Grupo Reconocido DGA T03_20R), and associated EU Regional Development Funds are gratefully acknowledgedPeer reviewedMultidisciplinary Digital Publishing InstituteMinisterio de Ciencia e Innovación (España)Agencia Estatal de Investigación (España)Gobierno de AragónEuropean CommissionGarcía-Bordejé, José Enrique [0000-0001-8158-1270]Dongil, Ana Belén [0000-0003-3445-5444]Guerrero-Ruiz, Antonio [0000-0003-1848-5985]Rodríguez-Ramos, Inmaculada [0000-0003-4622-6008]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202220222022info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/266284reponame:DIGITAL.CSIC.
