Cu<sub>3</sub>P/SnO<sub>2</sub> photocatalysts of various Cu<sub>3</sub>P loadings (10-40 wt% Cu<sub>3</sub>P) were synthesized using a combination of hydrothermal synthesis and a partial annealing method. Their photocatalytic activity was tested for tetracycline hydrochloride (TC-HCl) degradation under visible light irradiation. Cu<sub>3</sub>P/SnO<sub>2</sub> samples were characterized by X-ray diffraction (XRD), N<sub>2</sub>-adsorption, ultraviolet-visible diffuse reflectance spectra (UV-vis DRS), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The results showed that the p-n RSC advances33471-33480https://www.ebi.ac.uk/biostudies/studies/S-EPMC9042268biostudies-literatureSynthesis of Cu<sub>3</sub>P/SnO<sub>2</sub> composites for degradation of tetracycline hydrochloride in wastewater.PMC9042268Fan YZuo YWu QZhang YTontiwachwuthikul PShi HZheng TfalseSynthesis of Cu<sub>3</sub>P/SnO<sub>2</sub> composites for degradation of tetracycline hydrochloride in wastewater.Antibiotic drugs have become dominating organic pollutants in water resources, and efficient removal of antibiotic drugs is the priority task to protect the water environment.
