Abstract:
A method of manufacturing a filter comprising a substrate coated with an oxidation catalyst mixture, said filter configured to oxidize organic components within a fluid in the presence of electromagnetic radiation from an electromagnetic radiation source, said method comprising:providing said substrate, said substrate formed from a transition metal and configured so that said substrate may be positioned within a flow of fluid without substantially impeding said flow; combining a substantially nanophase component of metal oxide oxidation catalyst with a substantially microphase component of metal oxide oxidation catalyst to form said oxidation catalyst mixture, said mixture comprising at least 30% said nanophase metal oxide oxidation catalyst, said nanophase and microphase oxidation catalysts having the property of accelerating the oxidation of said organic components when said oxidation catalysts are exposed to electromagnetic radiation; adding said mixture to a liquid carrier to form a solution; and spraying said solution onto said substrate so that said solution is coated onto said substrate.
