Abstract
A catalyst for use in abatement of organic compounds, including noxious compounds in water, wherein the water in a first step is enriched with ozone/oxygen. The enriched water is then passed through a catalyst, consisting of activated carbon as carrier for metal oxides including iron oxide, cobalt oxide, nickel oxides, manganese oxide. Furthermore, the catalyst can contain one or more of the noble metals, preferably platinum or palladium. By the catalyst, undesired intermediate products from the ozone treatment are avoided. The catalyst is employed in a water treating plant and in a process for treatment of water.
