Recent Progress in Modification of Bipolar Membranes Water Dissociation Performance

Bipolar membrane is important for application in the fields of carbon capture,energy conservation,comprehensive utilization of resources, etc,due to its unique water dissociation properties and easy integration with other technologies. However,the existing bipolar membranes suffer from low water dissociation efficiency,poor selective permeability and stability,which severely limit the wide application. Therefore,a lot of research works have been carried out in recent years on the improvement of water dissociation performance. In this paper,the performances improvement and optimization strategies of bipolar membranes,have been reviewed from both domestic and international aspects including optimization of bipolar membrane ion exchange layers and interface layer catalyst and geometry control of bipolar membrane. The research progress of water dissociation catalysts,laws governing membrane structure were emphasized,providing outlook on the major challenges and future development directions in this field. The aim is to provide a reference for the development of bipolar membranes with high water dissociation performance, so as to promote their application in energy conversion and resource reuse. © 2024 Cailiao Daobaoshe/ Materials Review.
