Here, we report a significant enhancement in photo-activity of Titanium dioxide by combination of CoFe2O4 intoTiO2 structure. First, CoFe2O4, TiO2 and [email protected]
nanofibers were prepared via a combination of electrospinning method and in-situ polymerization. The morphology and crystalline structure of composite nanofibers were investigated using scanning electron microscopy (SEM) and X-ray diffraction, comprehensively. The advantage of combining CoFe2O4 with TiO2 has been accepted which it’s due to the magnetic activity of CoFe2O4 ferrites. By the way easier/faster separation of the photocatalysts after photo-oxidative process is occurred. The photocatalytic activities of the nanofibers were conducted by photo-oxidative decomposition of Direct Red 80 (DR80). Furthermore, the influence of some parameters that affect on dye removal including, nanofiber dosage, initial dye concentration and solution pH were studied to gain a maximum degradation. The results confirmed that initial dye concentration has the highest impact on the photo-degradation of DR80. Among the synthesized samples, [email protected]
composite demonstrated much higher photocatalytic activity as well as initial degradation rate.
