- METHOD FOR FABRICATING Ag-Pd ALLOY NANOPARTICLES

摘要

A method of preparing silver-palladium alloy nanoparticles is disclosed. The method for preparing silver-palladium alloy nanoparticles may include sequentially depositing a first metal layer made of a first metal and a second metal layer made of a second metal on a substrate; And heating and cooling the first metal layer and the second metal layer, and in the heating and cooling the first metal layer and the second metal layer, the first metal layer and the second metal layer are made of an alloy of the first metal and the second metal. A plurality of nanoparticles isolated from each other are formed, and the first metal and the second metal are all selected differently from one of silver (Ag) and palladium (Pd) and contained in the nanoparticles. The content ratio of the first metal to the metal is x, the content rate of the second metal is 1-x, the thickness ratio of the first metal layer to the total thickness of the first metal layer and the second metal layer is x, The thickness ratio of the second metal layer is 1-x.
