Abstract
A ceramic catalyst filter, a filtering system including the same, and a method of manufacturing the same. The ceramic catalyst filter includes: a single body ceramic filter including a first surface for blocking a first material and a second surface for removing the second material passing through the first surface; and a photocatalyst thin film including nanometer-scale grains coated on a surface of the ceramic filter.

A method of manufacturing a ceramic catalyst filter comprising a single body ceramic filter comprising a first surface for blocking a first material and a second surface for removing a second material passing through the first surface, and a photocatalyst thin film comprising nanometer-scale grains coated on a surface of the ceramic filter, the method comprising:
- preparing a coating solution comprising a self-assembly polymer and a photocatalyst precursor;
- coating the ceramic filter with the coating solution by dipping the ceramic filter in the coating solution;
- and
- drying and then heat-treating the ceramic filter coated with the coating solution,
- wherein the drying is performed in a vacuum oven at a temperature of 70 to 100° C.
