SINTESIS, KARAKTERISASI DAN UJI AKTIFITAS FOTOKATALITIK NANOKOMPOSIT TiO2-ZnFe2O4
Abstract: TiO2-ZnFe2O4
nanocomposite photocatalyst has been successfully synthesized by
coprecipitation/hydrolysis method. The nanocomposites were characterized by
Scanning Electron Microscopy-Electron Dispersive X-Ray (SEM-EDX), X-Ray
Diffraction (XRD), and Vibrating Sample Magnetometer (VSM). SEM images show
that the TiO2-ZnFe2O4 nanocomposite (1:0,1) has homogenous surface and particle
size. XRD pattern show that the highest intensity of anatase was TiO2-ZnFe2O4
nanocomposite (1:0,1) with highest calcination temperature, 600oC at 2θ =
25,26o. The present of ZnFe2O4 prevent transformation of anatase to rutil.
ZnFe2O4 showed the peaks at 2θ = 53,9o and 62,8o. Magnetic properties analysis
indicated that TiO2-ZnFe2O4 nanocomposite has soft magnetic property than ZnFe2O4.
Photocatalytic activity of TiO2-ZnFe2O4 nanocomposites in degradation of
Rhodamine B under solar light irradiation showed higher activity than ZnFe2O4
and TiO2 synthesized.
