How is Zirconia Prepared for Catalytic Applications?
The preparation of zirconia for catalytic applications typically involves several steps to optimize its surface properties and catalytic performance:
Precipitation: Zirconium salts are precipitated from aqueous solutions to form zirconium hydroxide, which is then calcined to produce zirconia. Doping: To enhance its catalytic properties, zirconia can be doped with various elements such as cerium, yttrium, or lanthanum. Doping can improve oxygen storage capacity and thermal stability. Surface Modification: Various surface treatments, including the introduction of acidic or basic sites, can be performed to tailor zirconia's surface properties for specific catalytic reactions.
