cerium acetylacetonate
}}
Cerium acetylacetonate is a compound with formula Ce(C5H7O2)3. It is the cerium complex of acetylacetone.
==Uses==
Cerium acetylacetonate is used in the formation of mesoporous nanocrystalline ceria using the sol-gel process. The cerium source can be cerium nitrate, acetate or acetylacetonate, but the unique properties of cerium acetylacetonate yield this effect: the shorter length of the stabilizer's hydrocarbon chain, the smaller the crystallite size in the end product. For the other two sources of cerium, the opposite was true: a short hydrocarbon chain in the stabilizer prevented coagulation of ceria particles in the sol. 〔("Formation of mesoporous nanocrystalline ceria from cerium nitrate, acetate or acetylacetonate" )〕
Cerium acetylacetonate can also be used along with gadolinium acetylacetonate to synthesize gadolinia-doped ceria (GDC) gel powders. They are the precursors in the sol-gel method. 〔("Synthesis of gadolinia-doped ceria gels and powders from acetylacetonate precursors" )〕
