Synthesis of copper metallic clusters using reverse micelles as microreactors

摘要: Reverse micelles are used to synthesize in situ nanometallic copper particles. In mixed reverse with hydrazine as a reducing agent, metallic particles formed. At low water content, small obtained. With increasing the size of cluster increases from 2 10 nm. The use pure surfactant molecules instead favors formation cylindrical By using sodium borohydride absence oxygen and at large (from 20 28 nm) clusters progressively disappear, forming oxide
