Abstract

In order to investigate the variation tendency of the morphology of gold nanoparticles in the N-Viny-Pyrrolidone (NVP) system, gold nanoparticles were synthesized under different operating conditions and the morphology were characterized and analyzed through TEM, UV-vis and XRD. As an example, the synthesis mechanism of triangular gold nanoparticles with NVP was studies. The results show that stable gold nanoparticles can be obtained using NVP as reductant and stabilizer, and NVP can induce non-isotropic growth of gold nanoparticles, which created the triangular and hexagonal gold nanodisks. Besides, the effect of reaction condition on the synthesis of gold nanoparticles was studied. Rod-shape gold nanorods and nanoparticles with support also can be synthesized in this system.
