Abstract
A high surface area support material is formed of an intimate mixture of carbon clusters and titanium oxide clusters. A catalytic metal, such as platinum, is deposited on the support particles and the catalyzed material used as an electrocatalyst in an electrochemical cell such as a PEM fuel cell. The composite material is prepared by thermal decomposition and oxidation of an intimate mixture of a precursor carbon polymer, a titanium alkoxide and a surfactant that serves as a molecular template for the mixed precursors.
