Research has been carried out on the synthesis of CuFe2O4/SiO2/NiO composites and its application on photocatalytic degradation of congo red dye. CuFe2O4 was synthesized using coprecipitation method, CuFe2O4/SiO2 by sol-gel method, and CuFe2O4/SiO2/NiO by hydrothermal method. The resulting CuFe2O4, CuFe2O4/SiO2, and CuFe2O4/SiO2/NiO were characterized using XRD, SEM-EDS, VSM, and UV-Vis DRS. Th…
