Herein, we are reporting bipolar membranes (BPMs) for water splitting. BPMs are sandwiched structure of anion-exchange layer (AEL) and cation-exchange layer (CEL) with a protein (lysozyme (LYS) or bovine serum albumin (BSA) as interfacial layer (IL). CEL and AEL were prepared by controlled sulphonation or chloromethylation (without chloromethyl methyl ether). Presence of acidic and basic groups in the IL facilitates the H+/OH- transport and act as proton/hydroxide buffer. Further, water dissociation efficiency of BPMs was also analysed by experimental results (I-V curves, chronopotentiometry, and electrodialysis). Data revealed high suitability of BPM-LYS for excellent catalytic activity and water dissociation. The experimental results (I-V) curves, chronopotentiometry, and electrodialysis) revealed high suitability of BPM-LYS for excellent catalytic activity and water dissociation.
