Effects of AgNO₃ Concentration on the Preparation of Nano-Silver

Abstract:

nanosilver powder has high surface activity, catalysis property and wide usage, so it is important to study its preparation method. In this paper, nanosilver powder was prepared with industrial AgNO₃ as raw materials, hydrazine hydrate as the reducing agent, polyvinylpyrrolidone (PVP) as the polymeric protective agent, polyethylene glycol as the dispersing agent by solution chemical reduction method. The effects of AgNO₃ concentration on the preparation of nanosilver were studied, and the final product was examined with TEM testing. The test results show that it can be obtained flake nanosilver with good performance by controlling the reaction conditions, such as dispersion, stability and crystal properties.
