Abstract :
In order to increase the surface area, mesoporous tungsten oxide has been synthesized. In this work, we have used mesoporous silica SBA-15 and KIT-6 as a template for the synthesis of different WO 3 mesostructures. This material shows a small particle size, about 5-20nm, and a high surface area. We have reported here the synthesis pathways of these mesoporous oxides and their structural and electric characterization.
