Platinum Nanoparticles as Potent Anticancer and Antimicrobial Agent: Green Synthesis, Physical Characterization, and In-Vitro Biological Activity

$AgNO_3$ has the characteristic is controlling the inhibition or promotion of particle growth by adsorbing onto specific facets of platinum nanoparticles. Therefore, in this study, $AgNO_3$ was added to control the shape of platinum nanoparticles during the liquid phase reduction process. Consequently, platinum cubes were synthesized when $AgNO_3$ of 1.1 mol% (with respect to the Pt concentration) was added into the solution. Platinum octahedrons were synthesized when 32 mol% (with respect to the Pt concentration) was added into the solution. These results demonstrate that the metal salt $AgNO_3$, effectively controlled the relative growth rates of each facet of Pt nano particles.

Electrooxidation of Methanol on the Platinum Nanoparticles Modified Platinum Electrode

Journal of Hebei Normal University (2007)

Dong Lian-hong

For the first time,the electrooxidation of methanol was investigated on the platinum nanoparticles-modified platinum electrode using cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS) techniques.The results demonstrated that the oxidation current of methanol was greatly enhanced due to the immobilization of platinum nanoparticles,and also indicated that the increased oxidation current was not only originated from the enhancement of electrode surface and nanoparticles of platinum had an peculiar catalysis for the methanol oxidation.

Hydridosilsesquioxane Modified Silica-Supported Platinum Nanoparticles

Chemistry of Materials (1996)

Howard A. Ketelson Michael A. Brook Robert Pelton Y. M. Heng

Colloidal silica modified with a hydridosilsesquioxane (HSiO3/2) layer reacted with Karstedt's catalyst, bis(1,3-divinyl,1,1,3,3-tetramethyldisiloxane) platinum(0), to give catalytically active surface-bound platinum nanoparticles with an average diameter of 2 nm. The supported platinum nanoparticles could be recycled through at least three consecutive hydrosilation reactions while maintaining their catalytic activity. It is postulated that the mesh microstructure of the grafted hydridosilsesquioxane layer supports and protects the supported platinum nanoparticles from aggregating into larger inactive platinum species.
