“…The casting solution consisting of resin, PVC, and montmorillonite (MMT) were casted layer-by-layer begun with an anion exchange layer and then followed by an interfacial catalyst layer and cation exchange layer. Prior to casting the next layer, the previous layer dried completely . The BPM from this study enhanced the acid-alkali production capacity of the BPM due to the presence of MMT as a catalyst at the interfacial layer.…”

The growing demand for clean energy has spurred the quest for sustainable alternatives to fossil fuels. Hydrogen has emerged as a promising candidate with its exceptional heating value and zero emissions upon combustion. However, conventional hydrogen production methods contribute to CO 2 emissions, necessitating environmentally friendly alternatives. With its vast potential, seawater has garnered attention as a valuable resource for hydrogen production, especially in arid coastal regions with surplus renewable energy. Direct seawater electrolysis presents a viable option, although it faces challenges such as corrosion, competing reactions, and the presence of various impurities. To enhance the seawater electrolysis efficiency and overcome these challenges, researchers have turned to bipolar membranes (BPMs). These membranes create two distinct pH environments and selectively facilitate water dissociation by allowing the passage of protons and hydroxide ions, while acting as a barrier to cations and anions. Moreover, the presence of catalysts at the BPM junction or interface can further accelerate water dissociation. Alongside the thermodynamic potential, the efficiency of the system is significantly influenced by the water dissociation potential of BPMs. By exploiting these unique properties, BPMs offer a promising solution to improve the overall efficiency of seawater electrolysis processes. This paper reviews BPM electrolysis, including the water dissociation mechanism, recent advancements in BPM synthesis, and the challenges encountered in seawater electrolysis. Furthermore, it explores promising strategies to optimize the water dissociation reaction in BPMs, paving the way for sustainable hydrogen production from seawater.

“…Eswaraswamy et al explored heterogeneous BPMs (HBPMs) with a cation-exchange resin and montmorillonite (MMT) nanoclay interface layer. 68 These HBPMs, synthesized using a layer-by-layer solvent casting technique with polyvinyl chloride (PVC) as a binder, showed enhanced water dissociation performance (Figure 6b). The inclusion of hydrophilic MMT nanoclay reduced the water dissociation potential, with the best performance observed at a specific MMT concentration.…”

Bipolar membrane electrodialysis (BMED) is a promising technology for the capture of carbon dioxide (CO 2 ) from seawater, offering a sustainable solution to combat climate change. BMED efficiently extracts CO 2 while generating valuable byproducts like hydrogen and minerals, contributing to the carbon cycle. The technology relies on ion-exchange membranes and electric fields for efficient ion separation and concentration. Recent advancements focus on enhancing water dissociation in bipolar membranes (BPMs) to improve efficiency and durability. BMED has applications in desalination, electrodialysis, water splitting, acid/base production, and CO 2 capture and utilization. Despite the high efficiency, scalability, and environmental friendliness, challenges such as energy consumption and membrane costs exist. Recent innovations include novel BPM designs, catalyst integration, and exploring direct air/ocean capture. Research and development efforts are crucial to unlocking BMED's full potential in reducing carbon emissions and addressing environmental issues. This review provides a comprehensive overview of recent advancements in BMED, emphasizing its role in carbon capture and sustainable environmental solutions.
