摘要
In order to increase the surface area, mesoporous oxides have been synthesized. In this work, we have used mesoporous silica SBA-15 and KIT-6 as a template for the synthesis of different semiconductor oxides: CeO2 and WO3. These materials show a small particle size, about 5-10nm, and a high surface area. As required increase the sensitivity when used for gas sensing applications. XRD and HRTEM studies reveal that the silica host has been completely removed; therefore, the nanowires constitute a self-supported superlattice. (c) 2005 Elsevier B.V. All rights reserved.
