Title
(EN) SYNTHESIS OF PLATINUM AND PALLADIUM QUANTUM WELL SIZE NANO-PARTICLES
(FR) SYNTHESE DE NANOPARTICULES DE PLATINE ET DE PALLADIUM DE LA TAILLE D'UN PUITS QUANTIQUE
Abstract
(EN)
A process for preparing quantum well size nano particles of platinum / palladium having particle size in the range of 2 to 10 nm, said process comprising the steps of adding ethylene glycol / glycerol to platinum / palladium salt solution, wherein ethylene glycol / glycerol acts as a combined dispersing medium, reducing agent and capping agent and heating the same at a temperature in the range of 100° to 140°C to obtain nano particles of platinum / palladium.
(FR)
L'invention concerne un procédé permettant de préparer des nanoparticules de platine/palladium de la taille d'un puits quantique comprise entre 2 et 10 nm. Ledit procédé consiste à ajouter un éthylène glycol/glycérol à une solution de sels de platine/palladium, l'éthylène glycol/glycérol agissant comme un milieu de dispersion combiné, un agent de réduction et un agent de coiffage; et à les chauffer à une température comprise entre 100° et 140 °C afin d'obtenir des nanoparticules de platine/palladium.
