Disclosed is a photocatalytic coating sol composition and the method for preparing the same. The photocatalityc coating sol composition comprising 0.1% to 20% by weight of a photo-catalyst, 0.1% to 10% by weight of an inorganic adsorbent, 1% to 20% by weight of an inorganic binder, 55% to 95% by weight of an organic solvent and if necessary 0.1% by weight to 10% by weight of a metal compound. Specifically, the present invention can remove harmful substances by coating photocatalytic coating sol composition prepared from photocatalyst, inorganic adsorbent, inorganic binder, metal compound and organic solvent on metal filter such as aluminum etc., and plastic filter such as polyethylene and polypropylene etc. used in environmental contaminants treatment system or air conditioning plant such as air-conditioner and air-cleaner, according to any one of and ordinary coating techniques such as spray method or dipping method etc. at room temperature.
