摘要： PURPOSE: A method for removing ozone using natural manganese ore catalyst having excellent catalytic activity under sever conditions is provided. CONSTITUTION: The method comprises the steps of (a) fabricating a catalyst made of natural manganese ore containing 60 to 95 wt.% of pyrolusite (β-MnO2) and 0.5 to 20 wt.% of iron oxide, wherein the catalyst contains 0.1 to 5.0 wt.% of transition metals such as Zn, Fe, Co, Ni, Cu, Au, Pt, Pd, and Rh and (b) treating air or gas containing ozone at a temperature in a range of room temperature to 200°C using the catalyst obtained in the step (a), wherein the natural manganese ore catalyst is fabricated by (a1) crushing the natural manganese ore into particles having a size of 0.1-50 micrometers, (a2) adding the transition metal to the particles, (a3) dispersing the natural manganese ore particles into water, thereby obtaining natural manganese ore slurry, and (a4) coating the natural manganese ore slurry on a structure such as pallet, saddle, cylinder and metal plate.
