Au Nanoparticles Prepared by Microwave Irradiation

Abstract:

Using 3.5 G PAMAM as a stabilizing agent, Au nanoparticles have been prepared by reducing HAuCl₄ with microwave irradiation. The influence of microwave irradiation at the same ratio of 3.5 G PAMAM to HAuCl₄ for the different time and at the different ratio of 3.5 G PAMAM to HAuCl₄for the same time on Au nanoparticles ́size and shape has been studied. Au nanoparticles were characterized by UV-vis spectra and TEM. At the same ratio of 3.5 G PAMAM to HAuCl₄, the microwave irradiation time has a little influence on the Au nanoparticles ́size and shape, meanwhile more dispersed Au nanoparticles were obtained with the appropriate increase of reactive time. At the same irradiation time, bigger and more aggregative Au nanoparticles were acquired as the ratio of 3.5 G PAMAM to HAuCl₄ was decreased.
