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. [2]

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. [3]

gollark: Ah, a free one, who cares then.
gollark: And probably worse than the one in my £100 server from ebay?
gollark: You are aware that that is six years out of date?
gollark: Wow, that must be awful.
