Abstract
In the present research the synthesis of gold nanoparticles (AuNPs) was established using the extract of Sedum praealtum. It should be pointed out that the conditions of synthesis directly influence the size, morphology, stability and physicochemical properties of the nanoparticles obtained. The extract of the plant was characterized by FTIR spectroscopy finding groups N-H, C-OH, who are credited with the reducing capacity of the ions AU+3. The AuNP’s obtained were characterized by UV-visible spectroscopy, observing plasmones absorbance between 530 and 550 nm characteristic of these nanoparticles, moreover they were characterized by SEM and was observed the nanometric sizes, the reduction capacity of the extract was evaluated by voltammetric study, observing the intervals of the processes of reducing and oxidation of the ionic species. Additionally, it was done the deposition of nanoparticles synthesized on a ceramic substrate in order to achieve its stabilization and then the nanocomposite was analyzed by SEM.
