Abstract:
A method of manufacturing a filter for decomposing organic components within a fluid as electromagnetic radiation is emitted from an electromagnetic radiation source onto said filter, said filter comprising a substrate and an oxidation catalyst suspended on said substrate, said substrate being formed from a transition metal and adapted to be positioned within a flow of a fluid without substantially impeding said flow, said 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, said mixture comprising at least 30% said nanophase metal oxide, said catalyst having the property of accelerating the oxidation of said organic components when said catalyst is exposed to said electromagnetic radiation, said method comprising the steps of:mixing said oxidation catalyst with water to form a solution;providing ultrasonic energy to said solution;adding a wetting agent to said solution;adding a polar solvent to said solution;spraying said solution onto said substrate; andbaking said, substrate at a temperature greater than 150.degree.
