More Information
Summary:An oxygen catalyst-containing structure comprising a first layer encapsulated by a second layer is provided, where the first layer includes an oxygen catalyst and the second layer is free of an oxygen catalyst. A method of making an oxygen catalyst-containing structure comprising a first layer and a second layer is also provided where the first layer includes an oxygen catalyst, the second layer is free of an oxygen catalyst, and the first layer is encapsulated by the second layer. The method includes impregnating a first solution containing a first superabsorbent polymer with an oxygen catalyst; allowing the first solution to gel to form the first layer; coating the first layer with a second solution containing a second superabsorbent polymer; and allowing the second solution to gel to form the second layer.
