Abstract:Zirconium dioxide (ZrO2) is an excellent catalytic material, due to its high-temperature resistance, corrosion resistance and high mechanical strength. Besides, it has both acid and basic sites on the surface and is able to produce oxygen vacancy. However, ZrO2 prepared by conventional methods has low surface area and pore volume, which may limit its broad applications. The recent preparation methods or techniques of high-surface-area ZrO2, including templating methods, MOF pyrolysis, and electrostatic spinning, so as to improve its thermal stability and to extend its applications in catalysis are reviewed. The studies showed that the porous ZrO2 can improve the dispersion of the supported metal and the metalsupport interaction, giving rise to the enhanced activity and stability of the catalysts. Meanwhile, its particle size, morphology and pore structure also have effects on the catalytic performance. The highefficient and low-cost preparation methods of thermal stable high-surface-area ZrO2, and the accurate regulation of its morphology or structure, will give it a broader catalytic application prospect in the future. ? 2019, Chemical Industry Press.
