The invention discloses a catalyst capable of eliminating ozone. The catalyst is prepared by the following steps of: (1) preparing honeycomb active carbon, namely adding 2 to 20 percent of zinc chloride into active carbon powder with 1,000 to 3,000 meshes, adding an adhesive consisting of sodium silicate, aluminum oxide powder, acetone and ethanol according to mass volume ratio of 1:0.5-3:2-5:10-20, stirring into a daub shape, performing pressure casting moulding and drying; (b) selecting heavy metal salt, which is highly soluble in water, to dissolve in water to prepare impregnation liquid, placing the honeycomb active carbon into the impregnation liquid to soak and drying, wherein the heavy metal salt content of the impregnation liquid is 2 to 3 percent (w/v), preferably 5 to 20 percent(w/v); and (c) adding the honeycomb active carbon prepared in the step (b) into aqueous alkali to soak, rinsing, draining and drying at the temperature of between 160 and 220 DEG C. The catalyst can effectively increase effective load in unit volume, and has high wet resistance, long service life, low cost, low wind resistance and no secondary dust pollution.
