In this sense, a series of catalysts has been prepared by thermal treatment of layered double hydroxides, hydrotalcite type, of Mg(II) and Fe(III), with different Mg/Fe molar ratios. The resulting mixture of metal oxides was characterized by X-ray diffraction, TEM, N2 adsorption-desorption, CO2-TPD, NH3-TPD and XPS, and then catalysts were tested in the Meenwein-Ponndorf-Verley (MPV) reduction of furfural to obtain furfuryl alcohol. The catalytic results show that the catalysts with a Mg/Fe molar ratio of 3 allows reaching the highest furfural conversion at a lower reaction time, with a FOL yield close to 90% after 6 h of reaction at 443 K. The detailed analysis of these catalysts also revealed that the basicity has a more predominant role in the MPV reaction than acid sites. eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Catálisis Hidrogenación Catalytic transfer hydrogenation of furfural to furfuryl alcohol over calcined MgFe hydrotalcites journal article
