Fabrication of Silver Nanostructures by Microwave-assisted Method

摘要

With polyvinyl pyrrolidone (PVP) as stabilizer and polyethylene glycol (PEG) as reducer, silver nanostructures were synthesized by microwave-assisted method. The morphology, size and crystal structure of silver (Ag) nanostructures were investigated by SEM and XRD. The results showed that the Ag nanostructures could change from nanoparticles to nanowires by introducing Cl~-. The growth speed of nanowires could be controlled by changing the reaction power, thus Ag nanorods and Ag nanowires with different length could be obtained.
