Abstract

The invention discloses nano-silver with modified sucrose as a reducing agent and a protective agent and a preparation method thereof. The method comprises the steps that the sucrose modified by periodate is slowly added into a AgNO3 solution, the sucrose modified by the periodate and the AgNO3 solution are mixed and stirred uniformly, and then reaction is carried out at the temperature of 80 DEGC for 12-24 hours so as to obtain nano-silver particles. According to the nano-silver and the preparation method thereof, the modified sucrose serves as the reducing agent and the protective agent forthe nano-silver particles, and therefore the nano-silver and the preparation method thereof have the characteristics of being wide in raw material sources, mild in reaction, green, environmentally friendly and the like.
