Abstract

Abstract This work investigates the use of MgFe mixed oxides, derived from layered double hydroxides (LDH) with Mg/Fe molar ratio ranging from 1 to 4, as base catalysts for the etherification of glycerol. LDH precursors and catalysts were characterized by XRD, XPS, CO 2-TPD, NH 3-TPD, N 2 adsorption and DTA–TG analysis. The MgFe mixed oxides exhibit excellent textural properties, with specific surface areas close to 200 m 2 g− 1 and ...
