1. A method for applying a photocatalyst onto a substrate useful in a photocatalytic oxidation air filtration system comprising the steps of:

  • a. mixing a metal oxide photocatalyst with a polymeric resin to form a photocatalyst-resin mixture;

    b. electrically charging the photocatalyst-resin mixture;

    spraying the photocatalyst mixture onto the substrate to form a metal oxide powder-coated substrate; and

    c. heating the photocatalyst powder-coated substrate.
