Abstract
The present invention describes the use of nanoparticle interfaces to chemically process solid nanomaterials into ones with tailorable core-void-shell architectures. The internal void sizes are proportional to the nanoparticle size, the shell thickness and composition, and can be either symmetric or asymmetric depending on the nature of the interface, each of which is controlled by the process of making.
Claims13
A nanoparticle, comprising layers of:
- an iron core;
- a chromium alloy shell forming having an outer oxide interface layer rich in chromium;
- a void between said iron core and said chromium alloy shell;
- and
- a metal positioned between the iron core and shell and at least partially filling the void;
- wherein the diameter of said nanoparticle is between about 15 and 25 nanometers.
