Preparation of ZnFe2O4@TiO2 Novel Core-Shell Photocatalyst by Ultrasonic Method and Its Photocatalytic Degradation Activity

ZnFe2O4 microspheres were prepared by solvothermal method, and a novel ZnFe2O4@TiO2 core-shell composite photocatalyst was ultrasonic (denoted as ZT-x) mechanical stirring ZTM-1.2). The morphology, structure, magnetic, optoelectronic properties of the catalyst investigated comprehensively, degradation performance explored through photocatalytic Rhodamine B (RhB) under UV light. concentration RhB 10 mg/L, 0.3 g/L. ZT-1.2 showed best activity, rate reached 97.3% within 60 min. ability further evaluated Methylene blue (MB), Methyl orange (MO), Phenol, Ofloxacin (OFX). also exhibited excellent stability. improved attributed to constructing Z-type heterojunction. Moreover, low-efficiency ZTM-1.2 caused agglomeration low TiO2 loading, confirming superiority method providing new for preparation magnetically recoverable TiO2-based photocatalyst.
