- 中文摘要: A novel material ZrO2/SiO2 was synthesized on a SiO2 support by means of electrostatic self-assembly technique and sol-gel method. After treating this material with 0.7 mol·L-1 H2SO4, a nanostructural solid superacid catalyst SO42--ZrO2/SiO2 was prepared. The material was characterized by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Brunauer Emmett Teller method (BET) and Hammett indicator method. The catalytic activity of the catalyst was carried out for the esterification between acetic acid and butanol. Results show that the catalytic activity of this catalyst was much higher than that of powdered superacid catalyst SO42-/ZrO2. Due to the SiO2 spherical support, the solid superacid catalyst could be separated and recovered easily. The nanostructural ZrO2/SiO2 will be a promising material for the chemical industry in the future.
