摘要：A detonation method for synthesizing carbon-encapsulated metal nanoparticles (CEMNPs) is reported.The composite precursors containing various nitrate dissolved in absolute ethanol is ignited by a nonelectric detonator in nitrogen gas in an explosion vessel.The material characteristics of these nanoparticles are then examined with the XRD,TEM,EDX and RS.The results show that the composite particles whose coating shell were graphite carbon could be dispersed finely.The core of nanoparticles were composed of iron,cobalt and nickel crystal to that of the above explosive precursors.
