چکیده
Bipolar membranes (BPMs) are recently emerging as a promising material for application in advanced electrochemical energy systems such (photo)electrochemical CO2 reduction and water splitting. BPMs exhibit unique property to accelerate dissociation ionic separation that allows maintaining steady-state pH gradient devices without significant loss process efficiency, thereby allowing broader catalyst selection the respective oxidation reactions. However, formation of high-performance with significantly reduced overpotentials driving at conditions rates relevant technologies is key challenge. Herein, we perform detailed assessment requirements base materials optimal design routes BPM layer interface formation. In particular, presents critical component its structure morphology influencing kinetics reaction governed by both electric field driven mechanisms. For this purpose, present, among others, advantages drawbacks utilization bulk heterojunction formed 3D structures have been reported demonstrate possibility designing stable BPMs. Also, outer layers play crucial role mass transport, particularly related ion transport electrolyte–membrane membrane–catalyst interfaces. This work aims identifying gaps structure–property current monopolar provide prospective facile excellent efficiency. It extends discussion about strategies systems.
