Abstract
Official abstract text for this publication.
Electrocatalysts having non-corrosive, non-carbon support particles are provided as well as the method of making the electrocatalysts and the non-corrosive, non-carbon support particles. Embodiments of the non-corrosive, non-carbon support particle consists essentially of titanium dioxide and ruthenium dioxide. Active catalyst particles of a platinum alloy are deposited onto each non-carbon composite support particle. The electrocatalyst can be used in fuel cells, for example.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrocatalyst, comprising: non-carbon composite support particles, each non-carbon composite support particle comprising titanium dioxide and ruthenium dioxide, wherein ruthenium dioxide nano-particles are non-uniformly deposited on a titanium dioxide nano-particle, forming uniformly located adhesion sites between the titanium dioxide and the ruthenium dioxide, wherein the titanium dioxide nano-particle has a first particle size and each ruthenium dioxide nano-particle has a second particle size, the first particle size and the second particle size being the same. 2. The electrocatalyst of claim 1 , further comprising active catalyst particles deposited onto the non-carbon composite support particles at the uniformly located adhesion sites. 3. The electrocatalyst of claim 1 , wherein the first particle size and the second particle size are one size selected between 10 and 40 nanometers.
