The Green Preparation of Nano-Silver Particle by Reductive Polysaccharide


Article Preview

Silver nanoparticles have been prepared using reductive polysaccharides (glucan) as protecting agents and silver nitrate as precursor via a facile green approach, and possible formation mechanism of silver nanoparticle was proposed in this paper. Silver nanoparticles appearance, size and size distribution were controlled by different synthesis technologies and reaction conditions. By changing the reaction conditions such as AgNO3 solution concentration, glucan dosage, reaction temperature, reaction time, the parameters affecting the product shape, particle size and size distribution were investigated. The samples synthesized were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis spectrophotometer (UV-vis) methods. The results have showed that nanosilver particle with different shapes such as rod-like, sheet-like or flake and tree-like etc. can be prepared by reductive polysaccharides, and it is a green preparation technology.
