摘要：

In the present paper, cost-effective zinc chloride has been utilized to synthesize zinc-based aerogel using the epoxide addition sol-gel process. After supercritical drying of wet gels with CO2, zinc-based aerogels have been prepared. With the subsequently thermal treatment in selected atmospheres and designed heating program, zinc oxide aerogel of high porosity, large specific area (125 m(2) g(-1)), narrow particle size distribution and excellent hexagonal structure was obtained. The microstructures and compositions of zinc oxide aerogels obtained in different atmospheres were characterized. The results showed that decreasing the ratio between oxygen and nitrogen contributed to the maintenance of monolithic aerogels and desirable microstructure. FTIR, XRD, and TG were applied to analyze the chemical and physical changes of the thermal treatment process. Those analyses are able to provide a reference for preparing other metal oxide aerogels. It should be a promising method to design new metal oxide aerogels with attractive nanoarchitectures.
