METHOD FOR PRODUCING NOBLE METAL-LOADED POWDER, NOBLE METAL-LOADED POWDER AND EXHAUST GAS PURIFICATION CATALYST

摘要

In the present invention, slurry is formed by mixing noble metal-supported powder particles (3) and a binder (4) with each other in a liquid (Step S 1 ), and the noble metal-supported powder particles (3) are dispersed by applying vibrations to the slurry (Step S2), and thereafter, the slurry is spray dried while keeping a state where the noble metal-supported powder particles (3) are dispersed (Step S3), whereby noble metal-supported powder (1) is produced. In the noble metal-supported powder (1) produced by such a method, pores through which exhaust gas flows are formed appropriately, and accordingly, exhaust gas purification performance can be enhanced.
