Abstract: A method ofseed-mediated controlled growth is used to preparednano-sized copper particles. The copper nano-particles are firstly reduced bythe sodium borohydride with little size, the nano-particles are used as seedparticles , copper ion can be reduced by the ascorbate ion , and autocatalyticgrowth on the seed particles quickly. The nano-particles are studied by SEM the result show that the nano-patircles possesses regular surface and averagesize are from 80~90 nm.
