Solid acid catalysts are superior to traditional liquid acids because they are noncorrosive, environmentally benign, and recyclable. In addition, nano-magnetic solid acid catalysts are preferable as they exhibit large specific surface areas together with good acidity and are also readily separated from the post-reaction mixture. Three component nano-magnetic solid catalysts TiO2-Al2O3-Fe3O4 and CeO2-Al2O3-Fe3O4 and a four component catalyst ZrO2-Al2O3-CeO2-Fe3O4 were synthesized by a co-precipitation method and were subsequently characterized by inductively coupled plasma-atomic emission spectroscopy, Brunauer-Emmett-Teller surface area analysis, X-ray diffraction, transmission electron microscopy, and thermal gravimetric analysis. Their catalytic activities were also evaluated in the esterification reaction of acetic acid with n-butanol. The results demonstrated that these rare earth-based magnetic nanocomposites exhibited good catalytic activity.
Graphical AbstractA series of multicomponents nano-magnetic solid catalysts of TiO2-Al2O3-Fe3O4 (TAF), CeO2-Al2O3-Fe3O4 (CAF), and ZrO2-Al2O3-CeO2-Fe3O4 (ZACF) were synthesized by a co-precipitation method. The obtained nano-magnetic catalysts were fully characterized and demonstrated good catalytic activity in the esterification of acetic acid and n-butanol.Figure optionsDownload full-size imageDownload as PowerPoint slide
