ABSTRACT:
A reactive membrane for simultaneous removal of heterogeneous and homogeneous impurities such as moisture, oxygen and organic compounds from gases is provided. The membrane comprises a substrate layer having a plurality of pores therein, at least one layer of carbon on the porous substrate layer and coating the pores thereof, and at least one reactive layer of a metal in reduced form capable of reacting with the impurities and chemically bonded to the carbon layer. A method of forming the same is also provided.
