A Green and Simple Route for the Controlled-Size Synthesis of Gold Nanoparticles Using Preyssler Heteropolyacid

The authors describe a facile procedure for size-controlled synthesis of gold nanoparticles based on the reduction of Au 3+ (HAuCl 4 ) using Preyssler heteropolyacid (H 14 [NaP 5 W 30 O 110 ]) under UV irradiation. Preyssler plays the role of green reducing agent and also efficient stabilizer. This...

Description
Summary:The authors describe a facile procedure for size-controlled synthesis of gold nanoparticles based on the reduction of Au 3+ (HAuCl 4 ) using Preyssler heteropolyacid (H 14 [NaP 5 W 30 O 110 ]) under UV irradiation. Preyssler plays the role of green reducing agent and also efficient stabilizer. This method allows the synthesis of uniform hexagonal nanoparticles with an average size that is tunable between 1.35 and 86.7 nm by varying the gold ion concentration, molar ratio of gold ion to Preyssler, and Propan-2-ol amount. The authors found that there is a critical ratio for [Au 3+ ]/[Preyssler] in which two opposing trends in the size of nanoparticles would happened.
