Abstract:
(EN) The present invention provides a method for producing core-shell particles including the steps of: adding a first metal salt and a first surfactant to a first solvent to form a first solution; adding a first reducing agent to the first solution to form core particles including the first metal contained in the first metal salt; adding the core particles, a second metal salt, and a second surfactant to a second solvent to form a second solution; and adding a second reducing agent to the second solution to form shells on the surfaces of the core particles, thus producing core-shell particles, wherein the first and the second surfactant are polyoxyethylene, polyoxyethylene sorbitan monolaurate, or polyoxyethylene oleyl ether, and the core-shell particles produced by using the same method.
(FR) La présente invention se rapporte à un procédé de production de particules à noyau-enveloppe comprenant les étapes consistant à : ajouter un premier sel métallique et un premier agent de surface à un premier solvant afin de former une première solution ; ajouter un premier agent réducteur à la première solution afin de former des particules à noyau comprenant le premier métal contenu dans le premier sel métallique ; ajouter les particules à noyau, un second sel métallique et un second agent de surface à un second solvant afin de former une seconde solution ; et ajouter un second agent réducteur à la seconde solution afin de former des enveloppes sur les surfaces des particules à noyau, produisant ainsi des particules à noyau-enveloppe. Les premier et second agents de surface sont du polyoxyéthylène, du monolaurate de sorbitane de polyoxyéthylène ou de l'éther oléylique de polyoxyéthylène, L'invention se rapporte également aux particules à noyau-enveloppe produites à l'aide de ce procédé.
