Ultrasound-Assisted Hydrothermal Synthesis of SrSnO3/g-C3N4 Heterojunction with Enhanced Photocatalytic Performance for Ciprofloxacin under Visible Light

In this work, an SrSnO3/g-C3N4 heterojunction with different dosage of SrSnO3 was fabricated by ultrasound-assisted hydrothermal approach and characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), photoelectron (XPS), scanning electron microscopy (SEM), transmission (TEM), UV-visible diffuse reflectance spectra (UV-Vis DRS), photoluminescence (PL). Ciprofloxacin adopted to assess the degradation performance, sample combined 40% eliminated 93% ciprofloxacin (20 mg/L) within 3 h under visible light, which is 6.6 1.7 times greater than for g-C3N4, respectively. Furthermore, 85% CIP extinguished after five cycles a photocatalytic process. Ultimately, possible mechanism dissected.
