Evaporation of metallic silver was performed in Ar, N2 and He using the ELV-6 electron accelerator. The obtained ultra-dispersed powders with a particle size of 70–80 nm were investigated by XRD, HREM and UV–Vis spectroscopy. The structure of Ag(Ar) powder was shown to differ substantially from that of Ag(N2) by the presence of small oxide-like species of 10–20 nm on the particle surface. Catalytic activity of the powders in the reaction of ethylene epoxidation was also studied.
