The Ni/Al3Fe1 catalyst was synthesized by the co-precipitation method at 28 mol% of Ni (Ni/(Ni + Al + Fe)) and a molar ratio of Al/Fe of 3/1. The prepared catalyst was calcined at different temperatures (500–750 °C). The obtained samples were tested for the aqueous phase hydrogenolysis (APH) of glycerol and characterized by several analytical techniques (ICP-OES, H2-TPR, XRD, N2-physisorption, NH3-TPD, STEM, FESEM, and TGA). The catalyst calcined at 625 °C was selected as the best sample due to its high acidity, metal dispersion, and catalytic activity; 1,2-propanediol was the highest carbon selectivity product. In addition, it experienced lower metal leaching than the catalyst calcined at 500 °C info:eu-repo/grantAgreement/ES/AEI-FEDER/CTQ2017-86893-R info:eu-repo/grantAgreement/ES/DGA-FEDER/T22-20R info:eu-repo/grantAgreement/ES/MCINN/PID2020-114985RB-I00 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 3.9 2023 CHEMISTRY, MULTIDISCIPLINARY 80 / 231 = 0.346 2023 Q2 T2 0.715 2023 Chemical Engineering (miscellaneous) 2023 Q1 Chemistry (miscellaneous) 2023 Q2 7.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lete, Alejandro (orcid)0000-0002-2866-9035 García, Lucía Universidad de Zaragoza (orcid)0000-0001-7115-9025 Ruiz, Joaquín Universidad de Zaragoza (orcid)0000-0002-2924-3095 Oliva, Miriam Universidad de Zaragoza (orcid)0000-0002-7179-3031 Arauzo, Jesús Universidad de Zaragoza (orcid)0000-0002-5959-3168 5005 555 Universidad de Zaragoza Dpto.
