Associate Professor Enling Tian published a research paper “Facilitating proton transport by endowing forward osmosis membrane with proton conductive sites in osmotic microbial fuel cell” in Chemical Engineering Journal (IF=16.744), DOI: https://doi.org/10.1016/j.cej.2022.138767

Inheriting the advantages of both MFC and FO, this OsMFC system not only simply degraded organic pollutants but could simultaneously accomplish high-quality water extraction and bioelectricity production. A major challenge of the OsMFC application is the sluggish proton transport from anode to cathode. To address this issue, proton conductive sites were introduced into the FO membrane by importing sulfonic acid radical groups. The results demonstrated that the proton transport flux and the performance of OsMFC improved after FO membrane modification. Meanwhile, the mechanism of proton transport has been elucidated. The proton migration was reinforced under the synergistic effect of improved water flux and electromigration derived from internal electric field. This method to mitigate the catholyte pH through self-buffering in situ would further open a novel avenue for OsMFC application in large-scale actual wastewater treatment.
