Claim Text:
1. A method for preparing a functionalized and re-metallized conductive membrane, the method comprising: electrochemically depositing a first metal layer on a surface of a conductive membrane to form a metallized conductive membrane; forming a functionalized conductive membrane configured as a first filtration membrane by contacting the metallized conductive membrane with a first solution comprising, either removing the first metal layer from the functionalized conductive membrane by subjecting the functionalized conductive membrane to one or more conditions suitable for removing the first metal layer from the functionalized conductive membrane; electrochemically depositing another metal layer on the surface of the conductive membrane having the first metal layer removed therefrom; and functionalizing the re-metallized conductive membrane by contacting the re-metallized conductive membrane with another solution comprising at least one second electrochemically active compound or at least one second surface-modifying compound effective to form the functionalized and re-metallized conductive membrane configured as a second filtration membrane; wherein the at least one second electrochemically active compound or at least one second surface-modifying compound is different from the at least one first electrochemically active compound or the at least one first surface-modifying compound, respectively.
