Synthesis of NiFe2O4/SiO2/TiO2 composites for the photocatalytic degradation of congo red dyes had been done. The application of NiFe2O4/SiO2/TiO2 synthesis was used to degrade Congo Red dyes by UV light. The result of Characterization using XRD, NiFe2O4/SiO2/TiO2 composite showed a sharp peak intensity at 2 = 35.74°and had a crystal size of 55.93 nm. The SEM-EDS result showed that the surf…
