Abstract:
The noble metal fine particle supported catalyst of the present invention includes a substrate, and a porous membrane formed on the substrate. The porous membrane contains support particles, noble metal fine particles, and an inorganic binder. In the porous membrane, the noble metal fine particles are supported on surfaces of the support particles, and the support particles form secondary particles each having a porous structure. The porous membrane is formed by binding, with the inorganic binder, the secondary particles formed of the support particles so that a gap is present at least partly between the secondary particles adjacent to each other.
