Abstract: The surfactant-free synthesis of a solid film of ceria was carried out at the air–water interface from an aqueous solution of Ce(NO₃)₃ and gaseous NH₃ as reactants. The synthesized CeO_2−x • n H₂O film consists of 2D nanocrystals with a fluorite structure. The film can form a planar coating on the surface of a solid substrate or transform into curved fragments upon drying, depending on the synthesis conditions.

Keywords: ceria, nanocrystals, films, interface, hydrolysis.
