Full TextAbstract
The authors describe a facile procedure for size-controlled synthesis of gold nanoparticles based on t he reduction of Au(HAuCl4) using Preyssler heteropolyacid (H14[NaP5W30O1103+]) under UV irradiation. Preyssler plays the role of green reducing agent and also efficient stabilizer. T his method allows the synthesis of uniform hexagonal nanoparticles with an average size that is tunable between 1.35 and 86.7 nm by varying t he gold ion concentration, molar ratio of gold ion to Preyssler, and Propan-2-ol amount. The authors found that there i s a critical ratio for [ Au3+]/[Preyssler] in which two opposing trends in the size of nanoparticles would happened.
