Formation of WOx-ZrO2 Isomerization Catalysts from Anion-Modified Zirconium Hydroxide
The formation of zirconia-based isomerization catalysts during thermal conversions of hydroxide modified with different amounts of tungstate groups has been studied by differential scanning calorimetry and X-ray diffraction analysis. The mechanism of formation of tungstated zirconia from a hydroxide precursor has been formulated.
