[b] Ocimum sanctum (Tulasi) Stem Extract Mediated Size Controlled Green Synthesis of Polyshaped Gold Nanoparticles and Its Application in Catalysis[/b]
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2013, Vol 3, Issue 2
Abstract
[i] The stem extract of Ocimum sanctum, a well known aromatic herb of great medicinal importance, has been used for the synthesis of gold nanoparticles at room temperature under very mild condition without any extra stabilizing or capping agents. The size of the nanoparticles could be controlled by varying the concentration of the stem extract. The gold nanoparticles were characterized by Surface Plasmon Resonance Spectroscopy, HRTEM, Energy dispersive X-ray spectroscopy and X-Ray diffraction studies. The catalytic activity of the synthesized gold nanoparticles has also been demonstrated[/i]
