RARE EARTH-NOBLE METAL-BASED COMPOSITE MATERIAL AND RARE EARTH-NOBLE METAL-BASED COMPOSITE OXIDE

摘要

PROBLEM TO BE SOLVED: To provide an oxide in which noble metals are homogeneously dispersed and which has high homogeneity.;SOLUTION: The rare earth-noble metal-based composite material comprises a hexacyano polynuclear complex crystal body that is represented by the general formula: Ln[M(CN)₆]nH₂O (wherein Ln is at least one kind of rare earth elements, M is at least one kind of trivalent transition metals, and n is 0 or more and 10 or less), and at least one kind of noble metal elements that are different from above M and their compounds as the second component.;COPYRIGHT: (C)2006,JPO&NCIPI
