Abstract:

Monolithic molybdenum trioxide aerogels and xerogels have been synthesized by the sol-gel method. A three-dimensional molybdenum oxide network is achieved by suppressing MoO bond formation through a ligand exchange process. Infrared spectroscopy is used to characterize the bond formations during gelation, aging, and drying of the gels. The as-prepared aerogels are low density 0.15-0.30 gcc amorphous materials with surface areas of 150- 180 sq mg. Upon heating to 400 deg C, the amorphous solids crystallize to orthorhombic MoO3.
