| 2 | Construction of Ag_(2)CO_(3)/BiOBr/CdS ternary composite photocatalyst with improved visible-light photocatalytic activity on tetracycline molecule degradation显示文摘Photocatalytic degradation was considered as a best strategy for the removal of antibiotic drug pollutants from wastewater.The photocatalyst of ABC (Ag_(2)CO_(3)/BiOBr/CdS) composite synthesized by hydrothermal and precipitation method.The ABC composite used to investigate the degradation activity of tetracycline (TC) under visible light irradiation.The physicochemical characterization methods (e.g.scanning electron microscopy (SEM),transmission electron microscopy (TEM),high resolution-transmission electron microscopy (HR-TEM),ultraviolet visible spectroscopy (UV),photoluminescence (PL) and time resolved photoluminescence (TRPL) clearly indicate that the composite has been construct successfully that enhances the widened visible light absorption,induces charge transfer and separation efficiency of electron–hole pairs.The photocatalytic activity of all samples was examined through photodegradation of tetracycline in aqueous medium.The photocatalytic degradation rate of ABC catalyst could eliminate 98.79% of TC in 70 min,which is about 1.5 times that of Ag_(2)CO_(3),1.28 times that of BiOBr and 1.1 times that of BC catalyst,respectively.The role of operation parameters like,TC concentration,catalyst dosage and initial pH on TC degradation activity were studied.Quenching experiment was demonstrated that·OH and O_(2)·-were played a key role during the photocatalysis process that was evidently proved in electron paramagnetic resonance (EPR) experiment.In addition,the catalyst showed good activity perceived in reusability and stability test due to the synergistic effect between its components.The mechanism of degradation of TC in ABC composite was proposed based on the detailed analysis.The current study will give an efficient and recyclable photocatalyst for antibiotic aqueous pollutant removal. | Kaliyappan Perumal Shajahan Shanavas Tansir Ahamad Annamalai Karthigeyan Padmanabhan Murugakoothan | 2023 | Journal of Environmental Sciences2023，，3： | 0 |
