The effectiveness of bifacial mixed metal-metal organic framework (MOF) anodes for municipal wastewater's photoelectro-catalytic (PEC) treatment has been rarely explored. Herein, pollutants removal efficiency from the municipal wastewater and the effect of operational parameters is verified under a visible range of light in a PEC system using TiO2–Bi(mixed metal)-MOF and TiO2–Sb(mixed metal)-MOF anodes, respectively. The comparable efficiency of pollutant removal from municipal wastewater in the PEC system with TiO2–Bi(mixed metal)-MOF anodes is high. At optimum operation parameters, TiO2–Bi(mixed metal)-MOF anodes in the PEC system play a positive role in the removal of micropollutants and the disinfection of municipal wastewater. This study reveals that PEC treatment of municipal wastewater contributes (35% of relative luminescence inhibition) to toxic biproducts. [Display omitted]
