摘要：

Copper clusters were produced by successive processes of oxidation and reduction of copper ultrafine particles. The oxide produced was cuprous oxide (Cu2O). Partly oxidized particles were converted to the original copper particles by the reduction Completely oxidized copper particles become a spherical shell composed of microcrystallites of cuprous oxide. By the reduction of spherical shell particles, microclusters of 2-10 nm in size were produced. In the reduction process of the oxidized particles, Cu4O structure particles can be observed.
