摘要

Vanadium oxide xerogels (V2O5.nH(2)O) were synthesized by hydrolysis of alkoxides. A surfactant of the nonylphenol family was added to the water-alkoxide mixture. The method was used to achieve better control of the deposition of the thin films by limiting gelation rate. The rate can be greatly modified in this way and control seems to be due to the encapsulation of the alkoxide by the surfactant as shown by V-51 NMR spectroscopy. After thermal treatment, xerogels have high porosity which was greater than that of classical V2O5 xerogels (60 m(2)/g instead of 2 m(2)/g) and the pore distribution is very homogeneous.
