Abstract
Official abstract text for this publication.
The alloy fine particles of the present invention are fine particles of a solid solution alloy, in which a plurality of metal elements are mixed at the atomic level. The production method of the present invention is a method for producing alloy fine particles composed of a plurality of metal elements. This production method includes the steps of (i) preparing a solution containing ions of the plurality of metal elements and a liquid containing a reducing agent; and (ii) mixing the solution with the liquid that has been heated.
First claim
Opening claim text (preview).
The invention claimed is: 1. Fine particles of a solid solution alloy, in which a plurality of metal elements are mixed at the atomic level wherein the plurality of metal elements are a plurality of metal elements that do not form a solid solution even in the liquid phase. 2. The alloy fine particles according to claim 1 , wherein the plurality of metal elements are two kinds of metal elements. 3. The alloy fine particles according to claim 2 , wherein elemental mapping using a scanning transmission electron microscope with a resolution of 0.105 nm demonstrates that there is no phase separation in the alloy fine particles. 4. The alloy fine particles according to claim 2 , wherein X-ray diffraction demonstrates that there is no phase separation in the alloy fine particles. 5. The alloy fine particles according to claim 3 , wherein the plurality of metal elements are silver and rhodium. 6. The alloy fine particles according to claim 3 , wherein the plurality of metal elements are gold and rhodium. 7. The alloy fine particles according to claim 1 , having an average particle size of 20 nm or less.
