Photocatalytic degradation of tetracycline hydrochloride by lanthanum doped TiO₂@g-C₃N₄ activated persulfate under visible light irradiation.

ABSTRACT: In this work, a visible light-driven La/TiO₂@g-C₃N₄ photocatalyst was synthesized for the photodegradation of tetracycline hydrochloride (TCH) in the presence of peroxydisulfate (PDS) in an internal loop-lift reactor. The surface morphology and structure of La/TiO₂@g-C₃N₄ have been characterized by XRD, SEM-EDS, FTIR, XPS, and UV/vis DRS. La/TiO₂@g-C₃N₄ displays outstanding photocatalytic performance and reusability. After four reuse cycles of the vis/La/TiO₂@g-C₃N₄/PDS system, the TCH degradation rate and efficiency still reached 0.083 min^-1 and 97.68%, respectively. Reactive species in this system included free radicals SO₄˙^-
