Abstract: A bias-free driven ion-based photoelectrochemical wastewater treatment system and method is disclosed. Through an ion-coupled photogenerated electron-assisted photocatalytic oxidation-reduction pathway, the system achieves efficient treatment of high-salinity wastewater. The system employs electron-ion receptor materials as the counter electrode, providing reaction sites to drive the coupling of photogenerated electrons and cation transfer. Additionally, the voltage generated by the system directly drives hole oxidation to produce strong oxidizing free radicals. Furthermore, this ion-based photoelectrochemical system demonstrates excellent degradation performance in high-concentration chloride media. This indicates that, in addition to cations (such as Na+) helping to accelerate the electron transfer rate, the presence of Cl? further enables efficient and sustainable wastewater treatment.
