High Efficient Photocatalytic Degradation of Methyl Orange Dye in an Aqueous Solution by CoFe 2 O 4 -SiO 2 -TiO 2 Magnetic Catalyst

This study successfully synthesized a core-shell-shell in the form of CoFe2O4-SiO2-TiO2 catalyst magnetic and recyclable. The catalyst for the photocatalytic degradation of methyl orange (MO) dye. Subsequently, the catalyst was subjected to XRD, FTIR, SEM-EDS, VSM, as well as UV-DRS characterization...
