A photocatalytic oxidation purification system includes an ultra violet light source and a filter that comprises a pleated wire mesh substrate with a nanophase metal oxide oxidation catalyst suspended on the substrate, wherein the catalyst is applied without an adhesive using an electromechanical plating process. As a fluid containing organic contaminants is directed through the filter in the presence of ultra violet light from the light source, the catalyst oxidizes and decomposes the organic contaminants into environmentally harmless components. Methods of making the purification system including preparing a solution of catalyst and applying the catalyst without adhesive binding material to the filter substrate electromagnetically.

[ What is claimed is:] [1.]1. A filter for decomposing organic contaminants within a fluid, said filter comprising a substrate having a plurality of cells and an oxidation catalyst suspended on said substrate so that the catalyst coats the walls of said cells, said oxidation catalyst comprising a mixture of nanophase metal oxide and microphase metal oxide, said mixture formed by adding together a substantially nanophase component of metal oxide and a substantially microphase component of metal oxide, wherein said mixture contains at least 30% of said nanophase metal oxide, said oxidation catalyst having the property of accelerating the oxidation of said organic contaminants when said oxidation catalyst is exposed to electromagnetic radiation, said substrate configured to support the nanophase metal oxide so as to maintain a high level of contact between the contaminants and the catalyst during fluid flow without substantially impeding the flow.
