Lanaya, Salaheddine published the artcileSulfated Well-Defined Mesoporous Nanostructured Zirconia for Levulinic Acid Esterification, Safety of Ethyl 4-oxopentanoate, the main research area is sulfated zirconia mesoporous nanostructure catalyst levulinic acid esterification.
Well-organized zirconia (ZrO2) nanoparticles forming mesoporous materials were successfully synthesized via a facile micelle-templating method using cetyltrimethylammonium bromide as a structure-directing template to control the nucleation/growth process and porosity. The systematic use of such a surfactant in combination with a microwave-assisted solvothermal (cyclohexane/water) reaction enabled the control of pore size in a narrow-size distribution range (3-17 nm). The effect of solvent mixture ratio on the porosity of the synthesized oxide was determined, and the controlled growth of zirconia nanoparticles was confirmed by means of powder X-ray diffraction, small-angle X-ray scattering, transmission electron microscopy, selected area electron diffraction, high-resolution transmission electron microscopy, XPS, thermogravimetric anal., and Fourier transform IR spectroscopy as well as N2 physisorption isotherm anal. Then, the as- prepared nanostructured zirconia oxides were treated with sulfuric acid to have sulfated samples. The catalytic performances of these mesoporous zirconia nanoparticles and their sulfated samples were tested for levulinic acid (LA) esterification by ethanol, with quant. conversions of LA to Et levulinate after 8 h of reaction.
