Abstract:
A method of manufacturing a filter for decomposing organic contaminants within a fluid as ultra violet light is emitted from a light source onto said filter, said filter comprising a substrate formed from a transition metal and an oxidation catalyst suspended on said substrate, said catalyst having the property of accelerating the oxidation of said organic contaminants when said catalyst is exposed to said ultra violet light, said catalyst comprising a mixture of nanophase metal oxide particles and microphase metal oxide particles, said nanophase metal oxide particles comprising at least 30% of a total of metal oxide particles of said mixture, said mixture generally comprising nanophase metal oxide particles coated onto microphase metal oxide particles, said method comprising the steps of:mixing said oxidation catalyst with a solvent to form a solution for application of said catalyst to said substrate; and applying the catalyst to said substrate electromagnetically.
