The magnetic BiOCl/ZnFe2O4 heterostructures was synthesized via a facile hydrothermal method.
BiOCl/ZnFe2O4 has photocatalytic efficiency for the degradation of penicillin G (PG) under visible-light irradiation.
A possible photocatalytic mechanism based on the BiOCl/ZnFe2O4 heterostructures has been proposed.
