Abstract:
A method of decomposing organic components within a fluid, comprising the steps of:providing a filter comprising a substrate having a plurality of cells and an oxidizing catalyst suspended on said substrate so that said catalyst coats the walls of said cells, said oxidizing 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 oxidizing catalyst having the property of oxidizing said organic components within said fluid when said oxidizing catalyst is exposed to ultra violet light;generating a flow of said fluid and directing said flow through said filter; andexposing the filter to ultra violet light, said ultra violet light exciting said oxidizing catalyst to oxidize and thereby decompose said organic components;wherein said substrate is adapted to be positioned within said flow without substantially impeding said flow.
