In situ hydrothermal fabrication of visible light-driven g-C 3 N 4 /SrTiO 3 composite for photocatalytic degradation of TC

A series of g-C N /SrTiO (CN/SrTiO ) composites with the different mass ratio of g-C N were prepared by facile in situ hydrothermal growth method, which was utilized to degrade tetracycline antibiotics (TC) under the visible light. The obtained samples were characterized by XRD, SEM, XPS, FT-IR, and...

Description
Summary:A series of g-C N /SrTiO (CN/SrTiO ) composites with the different mass ratio of g-C N were prepared by facile in situ hydrothermal growth method, which was utilized to degrade tetracycline antibiotics (TC) under the visible light. The obtained samples were characterized by XRD, SEM, XPS, FT-IR, and UV-vis DRS. The photocatalytic performance was also investigated in detail. The obtained 20% CN/SrTiO composite is sixfold of the pure SrTiO and twofold of the pristine g-C N under the visible light irradiation. This impressive performance of the heterojunction is ascribed to the effective restraint of the charge carrier recombination and expanded light absorption region. Moreover, the stability of the composite is also researched in detail. At last, a possible photocatalytic mechanism and charge carrier transfer pathway were further discussed.
