The proposed study shows for the first time that gaseous ammonia treatment of AgNO$_3$ and Ce(NO$_3$)$_3$ salts mixture aqueous solution surface gives rise to formation of a composite layer consisting of Ag(0) faceted colloidal crystals and nanoribbons, as well as CeO$_2$ nanocrystals. A study of such a composite carried out by FESEM, XRD, EDX, TEM, STEM and HRTEM methods has shown that the nanoribbons are about 50–150 nm wide and up to 2–3 $\mu$m long, and that there are 2–3 nm CeO$_2$ nanocrystals on the surface thereof. Colloidal crystals of about several micrometers consist of separate, almost identical silver nanocrystals about 20 nm in size. The obtained results provided a basis for construction of schemes of chemical reactions taking place during the synthesis, and gave grounds for recommendations on practical application of the obtained compounds.
Keywords: silver, colloidal crystals, nanoribbons, CeO$_2$, interface synthesis.
