Abstract:Nano-scale silver was prepared using the reduction reaction of silver nitrate by ethylene glycol with polyvinyl pyrrolidone(PVP) as the capping agent.The effect of reaction temperature and the concentration of AgNO3 and PVP on the shape of the nano-scale silver were studied.The nano-scale silver was characterized by XRD and TEM.The results indicated that certain shape nano-scale silver can be obtained by controlling the concentration of AgNO3 and PVP under the certain reaction temperature.
Keywords:nano - scale silver  PVP  shape - controlled
