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 °C2023http://zaguan.unizar.es/record/12575810.1039/d2ra07929ahttp://zaguan.unizar.es/record/125758oai:zaguan.unizar.es:125758info:eu-repo/grantAgreement/ES/AEI-FEDER/CTQ2017-86893-Rinfo:eu-repo/grantAgreement/ES/DGA-FEDER/T22-20Rinfo:eu-repo/grantAgreement/ES/MCINN/PID2020-114985RB-I00RSC Advances 13, 8 (2023), 5483-5495by-nchttp://creativecommons.org/licenses/by-nc/3.0/es/info:eu-repo/semantics/openAccess
