The upsurge of interest in the emergence of photocatalytic fuel cell systems(PFC)presents an efficient and environmentally friendly approach to wastewater treatment.In this work,a Z-scheme coupled with an S-scheme heterojunction electrode was used in the PFC,utilizing TiO2/GO/g-C3N4 as the photoan-ode and BiOAc1-xBrx/BiOBr as the photocathode.We systematically align the band structures between the anode and cathode,which facilitates the electron transfer between the electrodes.Our attempt suc-cessfully demonstrates that collaborative power generation facilitates the high efficiency of tetracycline hydrochloride(TC)degradation at both electrodes.The photoanode achieved a 94.87％degradation rate for TC,while the photocathode exhibited a 96.33％degradation rate after 2 h,surpassing pristine BiOBr and BiOAc by factors of～5.3 and～3.8,respectively.Furthermore,this work proposed a mechanism for electron generation,transport,and pollutant degradation mechanism in the PFC.Intermediate substances generated during the degradation of TC were analyzed through high-performance liquid chromatography-mass spectrometry(HPLC-MS)and ultraviolet photoelectron spectroscopy(UPS),while the optimal degra-dation pathway was confirmed using density functional theory(DFT).The findings of this work estab-lish the feasibility of efficiently degrading pollutants through PFC treatment,introducing a novel system where various heterojunctions in bipolar materials collaborate with photocatalysis to effectively generate electricity and enhance pollutant removal.
