description 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.
