| Description |
ZrO(2)-SiO(2) mixed xerogel and aerogel samples with varied molar ratios were prepared by sol-gel method followed by oven drying and supercritical drying using n-propanol as a solvent, respectively. Sulfation was carried out to further enhance the acidic properties of the mixed oxides. Effect of drying, Zr/Si molar ratio and sulfation have been studied and correlated with the structural, textural and catalytic properties of ZrO(2)-SiO(2) mixed oxides. Both xerogel and aerogel mixed oxides have different structural and textural features, however, the total number of acid sites per unit surface area (0.0021-0.0029 mmol NH(3) m(-2)) and thus the catalytic activity for cyclohexanol conversion (31-41%) was found in the similar range. Sulfated mixed oxide aerogel and xerogel samples showed significant enhancement of cyclohexanol conversion (91-99%).
