一般描述
Cerium(III) acetylacetonate is a crystalline powder used as an inorganic catalyst and as a precursor in solution and vapor deposition processes. It is valued for its redox-active cerium center, making it useful in catalytic applications and the fabrication of thin films and advanced materials. It is soluble in organic solvents, forms stable chelate complexes, and is valuable in applications such as the synthesis of nanostructured materials, glass polishing, and as a reagent in organic synthesis.
应用
Cerium(III) acetylacetonate hydrate can be used as:
- A precursor to synthesize ceria (CeO₂) nanopowders via the sol-gel process.
- A dopant precursor during the solvothermal synthesis of zinc oxide (ZnO) nanopowder to modify the structural and optical properties of the nanopowder.
- A precursor to synthesize gadolinia-doped ceria (GDC) via sol-gel synthesis.
特点和优势
- Thermally stable compound
- Soluble in various solvents
- Exhibits redox properties due to the Ce(III)/Ce(IV) couple, enabling participation in oxidation-reduction reactions
