Abstract
A catalytic structure is formed by first partially embedding discrete, non-conductive particles into the surface of an aluminum substrate. Nodules of a catalyst metal are then electrodeposited onto the surface between the embedded particles. The non-conductive particles control the distribution of the electrodeposited nodules. The aluminum substrate may be anodized after embedding the particles and the particles themselves may possess catalytic activity thereby providing a dual catalyst structure.
