dc.description.abstractSulfated titania (TiO2-SO42-) aerogel has been prepared through one-step synthesis by the sol-gel method using sulfuric acid as catalyst followed by the one-step CO2 supercritical extraction. Highly porous aerogel with a large surface area (469m2/g) and high porosity (pore volume 1.6cm3/g) has been obtained. Thermal evolution of the gels were evaluated by TGA-DTA, N2 adsorption, TEM and XRD, and the IR absorption spectra measurements were made to discuss the structure of sulfated titania. The anatase phase is stable after calcination at temperatures up to 700oC, and the specific surface area, total pore volume and average pore diameter of anatase phase do not change significantly after calcination at 600oC. Thermally stable and highly acidic sulfated titania aerogel is attractive as catalyst. The catalytic activity of the sulfated anatase shows better ability than Zeolite for application as a catalyst for etherification reaction of oleic acid (C18H34O2) with glycerol (C3H8O3) to produce glycerol mono oleate.en_US
