  • PLATINUM-TUNGSTEN SOLID SOLUTION PARTICLES AND CATALYST CONTAINING SAME
    Publication number: 20230226525
    Abstract: An object of the present invention is to provide platinum-tungsten solid solution particles that can be suitably used for catalyst applications and others. Another object is to provide a catalyst with higher catalytic activity than when platinum is used alone. Disclosed are platinum-tungsten solid solution particles comprising platinum and tungsten in solid solution at an atomic level. Also disclosed is a catalyst comprising the platinum-tungsten solid solution particles.
