Fabrication of a Z-scheme Bi2MoO6/NiFe layered double hydroxide heterojunction for the visible light-driven degradation of tetracycline antibiotics

摘要: Heterojunction catalysts offer promising potential for efficient and sustainable remediation of polluted environments. In this study, Z-scheme Bi2MoO6/NiFe layered double hydroxide (BMO/NiFe) heterojunction catalysts were synthesized using solvothermal process. The surface morphology, crystalline structure, and photochemical characteristics of the synthesized photocatalyst were analyzed by several spectroscopic and electron microscopy methods. BMO, NiFe and BMO/NiFe were efficiently utilized for tetracycline (TC) antibiotics degradation under visible light irradiation. The experimental findings suggest that the BMO/NiFe15 heterojunction catalyst greatly enhances the TC degradation rate to 95 % under 300 W visible light irradiation for 120 min. The rate constant of 0.0219 min−1 indicates a rapid degradation process following pseudo first-order kinetics. Furthermore, the effect of active free radicals, the …
