Title:
PLATINUM-TUNGSTEN SOLID SOLUTION PARTICLES AND CATALYST CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2021/256061
Kind Code:
A1
Abstract:
One purpose of the present invention is to provide solid solution particles of platinum and tungsten, which can be suitably used for a catalyst, etc. Another purpose of the present invention is to provide a catalyst having a higher catalytic activity than catalysts using platinum alone. Provided are platinum-tungsten solid solution particles in which platinum and tungsten are solid-dissolved at an atomic level. In addition, provided is a catalyst containing the platinum-tungsten solid solution particles.
