Cover Story: In this study, we developed a novel pore-filled anion-exchange membrane (PFAEM), enhanced with polypyrrole (PPy) and reduced graphene oxide (rGO), to elevate the energy harvesting efficiency in reverse electrodialysis (RED). The PPy/rGO layer effectively reduced the permeation of multivalent ions by controlling surface properties such as compactness and electrostatic repulsion. As a result, the PFAEM showed excellent monovalent ion selectivity and effectively suppressed the uphill movement of multivalent ions, improving the open-circuit voltage and power density of RED. The results of this study are also expected to provide valuable information for developing ion-exchange membranes with high monovalent ion selectivity required in a variety of electro-membrane processes. View this paper
