Preparation and Characterization of SiO₂-WO₃ Composite Aerogel by Ambient Pressure Drying Process

Abstract:

Using sodium tungsten and industrial water glass as raw materials, SiO₂-WO₃ composite aerogels were prepared by ambient pressure drying process. The hexamethyldisilazane(HMDSZ)/hexamethyldisiloxane(HMDSO)/hexane mixing solution was used to modify the sol-gel-derived SiO₂-WO₃ wet gel. The microstructure, morphology and pore characteristics of the obtained SiO₂-WO₃ composite aerogels were investigated by XRD, SEM, FTIR and BET N2 adsorption-desorption analysis. The adsorption/photocatalytic degradation for Rhodamine B of SiO₂-WO₃ composite aerogel was investigated. The results indicate that mesoporous SiO₂-WO₃ composite aerogel with specific surface area 660.8 m²/g and pore volume 1.94 cm³/g could be prepared by using HMDSZ/HMDSO/hexane mixing solution to modify the wet gel. The obtained SiO₂-WO₃ composite aerogels have good adsorption/photocatalytic degradation for Rhodamine B than that of pure WO₃ aerogel.
