Doped Nano Cobalt Oxides: Improvement of Photophysical Properties and Recycling Process via Photodegradation of Congo Red Dye
This study aimed to synthesize pure and metal-doped Co₃O₄ nanoparticles and evaluate the influence of Ni mono-doping and Cu/Ni or Cd/Ni co-doping on their structural, morphological, optical, magnetic, surface, and visible-light photocatalytic properties toward Congo Red (CR) removal. Pure Co₃O₄ and Ni-, Cu/N...
