Preparation and Photocatalytic Activity of Copper-supported Nickel Ferrite
In order to effectively solve the problem of antibiotic pollution in water,photocatalytic degradation technology is an indispensable part of today's sewage treatment field.Nickel ferrite(NiFe2O4),as a spinel ferrite material,is widely used in photocatalytic environmental pollution control.In this paper,copper(Cu)composite NiFe2O4 photocatalytic materials with different copper content were prepared by a simple hydrothermal method.Tetracycline hydrochloride was used as the target degradation material under simulated sunlight irradiation for 60 min,and its degradation rate was measured.In the prepared samples,17％-Cu@NiFe2O4 has the best tetracycline degradation efficiency,reaching 96％,and the degradation rate is 31％higher than that of pure phase NiFe2O4.
