SUPPORTED METAL CATALYST - UNIV YAMANASHI

Title:

SUPPORTED METAL CATALYST

Document Type and Number:

WIPO Patent Application WO/2022/145349

Kind Code:

A1

Abstract:

Provided is a supported metal catalyst that has an electrical conductivity permissible as a catalyst and that is capable of inhibiting generation of hydrogen peroxide.　The present invention provides a supported metal catalyst comprising: a carrier powder; and fine metal particles that are supported by the carrier powder. The carrier powder is an aggregate of fine carrier particles. The fine carrier particles each have a chain portion that is formed by fusion bonding of a plurality of crystallites into the form of a chain. The fine carrier particles are formed of a metal oxide. The metal oxide includes cerium. The supported metal catalyst has an electrical conductivity of at least 10-4 S/cm.
