Novel magnetically separable Fe3O4@CQDs photocatalyst: Cytotoxicity effects and photocatalytic performance
Source abstract
Abstract
The modified Fe3O4nanoparticles (NPs) with carbon quantum dots (CQDs) were prepared as a new heterogeneous photocatalyst through the hydrothermal method fromCordia myxa L.fruit extract. The structure, morphology, and magnetic properties of Fe3O4@CQDs were investigated using FT-IR, FESEM, EDX, XRD, TEM, and VSM analyses. The synthesized Fe3O4@CQDs photocatalyst has been applied to degrade tetracycline (TC). Also, the effective parameters in the photocatalytic process such as pH, photocatalyst concentration, and concentration of TC were investigated. By performing the photocatalytic process and applying the optimized conditions, it was observed that the degradation percentage of TC was obtained at 93.2% after 40 min. The cytotoxicity of the photocatalyst was examined on the Huh-7 cell line by the MTT assay and the IC50value was about 500 μg/mL.Graphical AbstractHarnessing Magnetism: Investigating the Cytotoxicity and Photocatalytic Efficiency of Fe3O4@CQDs
