MgO nanoparticles (NPs) were successfully fabricated by a facile, inexpensive and green synthesis protocol using soluble starch as a green bio-template. The influence of calcination temperature on its textural properties and catalytic efficiency has been investigated in detail. The enhancement of MgO NPs crystallinity by increasing the calcination temperature is found from X-ray diffraction (XRD) and Transmission electron microscopy (TEM) analyses. N2-sorption studies and CO2-temperature programmed desorption (TPD) measurements revealed that the MgO NPs calcined at 500 °C have superior textural properties and strong surface basicity. X-ray photoelectron spectroscopy (XPS) analysis conferred that the MgO-500 NPs furnished the optimized surface Lewis sites, consequently outperforms better transesterification activity. The fabricated MgO-500 NPs exhibited an excellent catalytic activity towards the efficient conversion of glycerol to glycerol carbonate (GC) with more than 93% selectivity. The intelligibility of the adopted synthesis is eco-benign and wide utility as a solid base catalyst for several organic transformations. © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

Synthesis of Biodiesel using the Mg/Al/Zn Hydrotalcite/SBA-15 Nanocomposite Catalyst

A series of efficient and robust Cu based mixed oxides were synthesized by a simple co-precipitation method and utilized for the production of glycerol carbonate (GC) via transesterification of glycerol with dimethyl carbonate (DMC). The synthesized materials were characterized using XRD, UV–vis spectroscopy, SEM, TEM, N2 sorption, CO2-TPD, and XPS. The addition of Cu on Mg/Al mixed oxides exhibits significant changes in its physicochemical properties and catalytic activity. The obtained mixed oxides showed remarkably high transesterification activity towards the efficient conversion of glycerol to GC under economical reaction conditions without using any solvent. Among all the catalysts employed, highest catalytic activity was observed over MAC-0.6 catalyst with glycerol conversion of 96.4% and GC yield of 91.2%. The improved catalytic performance was observed mainly due to the optimized catalyst molar ratio and strong surface basicity. The strong surface basic sites were greatly attributed to the incorporation of Cu2+ cations in the MgAl (O) periclase that efficiently catalyzed the transesterification of glycerol with DMC. Furthermore, the reported catalyst was robust and could be recycled for more than five times without any significant loss in its catalytic activity. © 2018 Elsevier B.V.
