In this study, the synthesis of CoFe2O4/SiO2/NiO composites was carried out for the photocatalytic degradation of methylene blue dye. The synthesized materials were characterized using XRD, SEM-EDS, VSM, and UV-VIS DRS. Characterization results using the XRD tool shows the highest intensity was located at 2θ = 43.25° with a crystal size of 2.41 nm. Characterization results using the SEM-EDS t…
