Zirconia-derivative materials attract much attention in catalysis as a a catalyst due to their acidity, redox site and metal support interaction. In the present work, various zirconia-derivative mesoporous molecular sieves such as zirconium chromate, zirconium silicate and zirconium phosphate have been prepared using surfactant micelle as a supramolecular template. X-ray diffraction and N2 adsorption studies indicate that the mesoporous materials have high surface area (~ 400 m2g-1), mesoporosity (~ 2 nm in diameter) and good thermal stability (up to 800 oC). These properties show possibilities of the materials for practical applications.
