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