Abstract

This study aims to analyze the syntheses of gold nanoparticles with different reducing agents: Sodium Citrate and Sodium Borohydride. The syntheses were characterized by Ultraviolet-visible Spectroscopy and the Fourier Transform Infrared Spectroscopy, in which we evaluated the influence of the reducing agent and the reaction agitation. The test results indicated the presence of metallic gold and confirmed the formation of gold nanoparticles. Finally, we composed a table showing the differences between the characteristics of the two reducing agents.
