An aircraft environmental control system includes a catalytic converter having ozone-destroying capability. A surface of the catalytic converter (22) is anodized to form an anodized layer (24), and the metal oxide layer is washcoated to form a washcoat layer (26). An ozone destroying catalyst (28) is impregnated in the anodized and washcoat layers. The catalyst may include one or more metals. For example, a bimetallic catalyst may include a precious metal and a transition metal. |
