Syntheses of Silver Nanofilms, Nanorods, and Nanowires by a Microwave-polyol Method in the Presence of Pt Seeds and Polyvinylpyrrolidone

AgNO3 was reduced by ethylene glycol (EG) in the presence of Pt seeds and polyvinylpyrrolidone (PVP) under microwave heating. In addition to spherical nanoparticles, single-crystalline silver nano-films, rods, and wires were produced. The relative number ratio of nanorods and nanowire to the total silver nanostructures was <14%. The formation mechanism of anisotropic silver nanostructures was discussed.
