DISPERSION LIQUID OF COMPOSITE PARTICLES, AND METHOD FOR PRODUCING SAME

摘要

The objective of the present invention is to provide a dispersion liquid of metal particles that is for producing an exhaust-gas purifying catalyst in which the aggregation of catalyst metals during high-temperature endurance is suppressed. The aforementioned objective can be achieved by a dispersion liquid comprising a dispersion medium, an organic base having a molecular weight of from 30 to 500, and composite particles that are dispersed in the dispersion medium and that include a first metal and a second metal, wherein: the first metal is palladium and/or platinum; and the second metal is a metal having a higher melting point than the melting point of the first metal.
