Description:
Microwave-assisted (MW) spontaneous reduction of noble metal salts, silver (Ag), gold (Au), platinum (Pt) and palladium (Pd) is reported using sugar solutions such as -D glucose, sucrose and maltose, etc. to generate nanomaterials. These MW-assisted reactions, conducted in aqueous media, proceed rapidly and reduction gets completed within 30 to 60 seconds depending on the sugar solution used. Maltose and sucrose solutions yielded different shapes such as prisms, hexagons, etc. whereas in case of -D glucose, spherical nanoparticles were obtained. The as-synthesized different shape nanostructures were characterized using UV spectroscopy, scanning electron microscopy, and transmission electron microscopy.
