Method for producing metal catalyst capable of uniformly highly dispersing metal particles

Highly dispersible in various carriers

Overview

　Precious metals are used as catalysts in various reaction systems, but their high price and scarcity have reduced their usage. Therefore, catalysts loaded with precious metals are generally prepared by dispersing and carrying noble metal particles in a nanoparticulate state on a support such as an oxide to maximize the surface area per amount of precious metal used. Conventional methods for producing noble metal catalysts have a problem that the dispersion of noble metal particles is poor and the particle size is uneven because the noble metal particles agglomerate during the heating process during metallization. Even if a method for producing a metal catalyst that can obtain highly dispersed particles is used, there is also a problem that the support is limited.　
　The present invention has made it possible to provide a method for producing a metal catalyst that can uniformly and highly disperse metal particles on various supports.
