“…The similar phenomenon was also observed in our previous study. 5 Meanwhile, it could be observed that the voltage drop of various membranes follows the order of CMX > CJMC-3 > TWEDC > CJMC-5. This trend is generally consistent with the observed area resistance of those cation-exchange membranes as listed in Table 2.…”

Bipolar membrane electrodialysis (BMED) is an environmentally friendly, high-effective technique for the cleaner production of gluconic acid. However, the unsatisfactory purity and low concentration of the regenerated base limit the applicable field of the byproduct for further utilization. In this study, BMED was applied for the cleaner production of gluconic acid from the perspective of the regenerated base. First, four types of cation-exchange membrane were screened for the BMED process by evaluating the performances of current efficiency, purity of regenerated base, and energy consumption. The BMED performances follow the order of CMX > TWEDC > CJMC-5 > CJMC-3. Furthermore, the effects of current density, the volume ratio between salt and base compartment on the BMED performances were optimized. A high base purity of 96.6% was obtained at a current density of 40 mA/cm 2 , while a high base concentration of 4.58 mol/L could be reached by applying a high volume ratio of 5:1 between the salt and base compartment. Moreover, the mechanism on the leakage of organic salts into the regenerated base was elucidated. The purity of the regenerated base was attributed to diffusion and electromigration. Diffusion dialysis experiments demonstrated that the permeability of gluconate through the CMX was 4.7 times of that through the BP-1. It was also found that the leakage of gluconate into the base could be alleviated at a low current density ranging from 20 to 50 mA/cm 2 . Finally, the regenerated base was subjected to the enzyme catalyst experiment for conversion of glucose into gluconate. This proof-of-concept study demonstrates that the regenerated base from the BMED process could be valorized to the upstream route for a closed-loop cleaner production.

Vanadium is an important soft metal that is widely used for various industrial sectors. However, the traditional ammonium precipitation of vanadium generates a large amount of waste salt, which is a great burden to the environment. In this study, an electrochemical method for the production of vanadium pentoxide was proposed using the bipolar membrane electrodialysis (BMED) technique. By precisely regulating the pH and vanadium salt concentration, the vanadate salt, predominantly V 2 O 7 4− , could migrate through the anion-exchange membrane and combine with protons generated by water splitting in the bipolar membrane. The effects of current density, initial NaVO 3 concentration, and volume ratio between the acid and salt chambers on the BMED performances were investigated. It was found that successful completion of the experiment was highly dependent on the migration of V 2 O 7 4− and the generation of H + /OH − by water splitting in the bipolar membrane. The competition between OH − and V 2 O 7 4− across the anion-exchange membrane is advantageous to help the acid compartment to become not too much acidic but is also a disadvantage to the vanadium BMED performance. Additionally, the quick supply of protons or the fast migration of vanadate might lead to the easy conversion of the polyvanadate H 2 V 10 O 23 4− into the suspended solid V 2 O 5 . Under the current density of 30 mA/cm 2 , the NaVO 3 concentration of 0.3 mol/L, and the volume ratio between acid and salt compartments of 1:2, the vanadium concentration in the acid chamber reached 0.168 mol/L with the conversion rate of 17.29%. The energy consumption could be as low as 13.52 kWh/kg V 2 O 5 . The purity of the V 2 O 5 product via the BMED method was 98.05%, which meets the industrial standards for practical use. Therefore, the proof-of-concept experiment well proved that BMED is capable of one-step converting the vanadium salt into vanadate acid, creating possibilities for the avoidance of the vanadium ammonium precipitation procedure.

Electrochemical devices allow the conversion and storage of renewable energy into high‐value chemicals to mitigate carbon emissions, such as hydrogen production by water electrolysis, carbon dioxide reduction, and the electrochemical synthesis of ammonia. Independent regulation of the electrode pH environment is essential for optimizing the electrode reaction kinetics and enriching the catalyst species. The in situ water dissociation (WD, ) in bipolar membranes (BPMs) offers the possibility of realizing this pH adjustment. Here, the design principles of high‐performance polymeric BPMs in electrochemical device applications are presented by analyzing and connecting WD principles and current–voltage curves. The structure–transport property relationships and membrane durability, including the chemical and mechanical stability of the anion‐ and cation‐exchange layers as well as the integrality of the interfacial junction, are systematically discussed. The advantages of BPMs in new electrochemical devices and major challenges to break through are also highlighted. The improved ion and water transport in the membrane layer and the minimized WD overpotential and ohmic loss at high current densities are expected to facilitate the promotion of BPMs from conventional chemical production to novel electrochemical applications.
