Wet-chemical synthesis of nanostructured Ce-doped mixed metal ferrites for the effective removal of azo dyes from industrial discharges

Tehmina Kousar et al.

Summary: Photocatalysis is a cost-effective and environmentally friendly technique for addressing water pollution caused by industrialization. In this study, Ce-doped cobalt/nickel mixed metal ferrite materials were synthesized using the microemulsion method. The C-9@CNMF material exhibited better mineralization of the CR dye, faster mineralization rate, and excellent recyclability and photo-corrosion resistance. These superior photocatalytic properties are attributed to the nanoarchitecture, larger specific surface area, tunable bandgap, and effective charge separation characteristics of the C-9@CNMF sample.
