Ordered mesostructured mixed metal oxides: microporous VPO phases for n-butane oxidation to maleic anhydride
High surface area (similar to 250 m(2)/g) microporous VPO phases were prepared from the VPO/surfactant mesophases by a two-step postsynthesis treatment, consisting of a Soxhlet extraction and thermal activation in reducing atmosphere at 400 degreesC. The resultant microporous VPO phases were studied in the partial oxidation of n-butane to maleic anhydride.
