Abstract

Nowadays, cobalt-based catalysts are becoming increasingly attractive for various reactions. In this work, the catalytic and photocatalytic activities of different cobalt ferrites were investigated for the degradation of phenol in water at neutral pH. Pure CoFe₂O₄ and mixed Co_xNi_1-xFe₂O₄ ferrites were synthesized using different precursors (chloride and nitrate). CoFe₂O₄ catalysts derived from chloride precursors showed a higher catalytic efficiency compared to those derived from nitrate precursors. Significant enhancement in the catalytic activities was observed when Ni was incorporated into CoFe₂O₄. Furthermore, the catalytic activities of phosphorus-modified cobalt ferrites (P-CoFe₂O₄) significantly improved the photocatalytic degradation of phenol.
