Title:
LAYERED MANGANESE OXIDE, AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/191337
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a catalyst having high catalytic activity such as an oxygen reduction reaction and a hydrogen generation reaction, and particularly, providing a catalyst using platinum group particles having a small particle diameter. This layered manganese oxide contains platinum group metal particles between layers. Provided is a method for preparing platinum group metal particles or a layered manganese oxide containing platinum group metal particles between layers, the method comprising introducing a platinum group complex between layers of the layered manganese oxide and reducing the introduced platinum group complex by electrolysis, wherein the potential applied to the platinum group complex is changed in the positive direction and the negative direction.
