TERNARY METALLIC COLLOID HAVING THREE LAYER CORE/SHELL STRUCTURE AND METHOD FOR PRODUCING TERNARY METALLIC COLLOID

摘要

PROBLEM TO BE SOLVED: To provide a ternary metallic colloid in which three kinds of metal atoms can be designed and arranged under good arranging state of the three kinds of metal atoms, and its producing method. SOLUTION: This ternary metallic colloid is composed of three different kinds of metal elements and contains metallic nano grains having three layer/shell structure. The metallic colloid can be produced by mixing a metallic colloid containing metallic nano grains having the core-shell structure composed of two kinds of metallic elements and a metallic colloid containing metallic nano grains composed of the metallic element different from two kinds of metallic elements. A catalyst produced from the metallic colloid produced with this method, has extremely high catalytic activity. COPYRIGHT: (C)2005,JPO&NCIPI
