In this study, bipolar membranes (BPMs) for efficient and long-term stable water dissociation were fabricated and characterized. Thin reinforced BPMs were prepared by casting sulfonated ionomer solution (sulfonated poly(ether ether ketone), SPEEK) on a pore-filled anion-exchange membrane which is fabricated by filling a styrene-based ionomer into a porous polyethylene substrate. In addition, Fe(OH)3, Fe(OH)2-EDTA, Fe(OH)3@TiO2, Fe(OH)3@Fe2O3, and Fe3O4@ZIF-8 were investigated as catalysts to facilitate water dissociation in BPM. The prepared BPMs were also systematically characterized to determine the optimum composition of the transition metal catalysts.
