Abstract
A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.
