Abstract
A photocatalytic metal deposition process and a resulting nanocomposite are described. The nanocomposite includes an electrically conducting carbonaceous material, a photoactive metal oxide and a metal. Metals for deposition include noble metals, metal alloys and other transition metals in which the metal is laid down precisely and in a predetermined fashion on one or more surfaces of a composite. Deposition provides a high performance electrocatalyst for a number of suitable applications.
