Abstract: The devices, systems and techniques disclosed in this patent document include photocatalytic filter devices and can be used to provide a method for manufacturing a photocatalytic filter with improved adhesion. In addition, the present disclosure of this patent document includes technology to provide a method for reactivating a photocatalytic filter. Using the disclosed techniques, even if a photocatalytic filter is contaminated, the contaminated photocatalytic filter is easily reactivated while maintaining improved adhesion.

Abstract: An photocatalytic filter is provided to include a support; and a photocatalytic material coated on the support to cause a photocatalytic reaction to degrade an undesired gas present in an air, and wherein the photocatalytic filter has cells with a width equal to or less than 2 mm, thereby providing an air resistance in a direction facing UV LED for the photocatalytic activation, the air flow having a minimized air resistance.

Abstract: The present disclosure relates to a photocatalytic filter, the surface of which has enhanced adsorption performance so that mixed gases including a gas that reacts later in a competitive reaction can be degraded from the initial stage of a photocatalytic reaction, and to a manufacturing method thereof. The method includes: dispersing carbon dioxide (TiO2) nanopowder as a photocatalyst and one or more metal compounds in water to prepare a photocatalytic dispersion; coating a support with the photocatalytic dispersion; drying the coated support; and sintering the dried support. The photocatalytic filter includes a support, and a photocatalyst and one or more metal compounds, which are coated on the support. The metal compounds include nanopowers of an iron (Fe) compound.
