摘要
A novel and facile approach for one-pot synthesis of spinel cobalt ferrites (CoFe₂O₄) nanoparticle (NPs) and is photocatalytic activity for degradation of pharmaceuticals waste and organic dye. The synthesis involves homogeneous chemical precipitation followed by hydrothermal heating, using of hexamine as a hydroxylating agent. As-synthesized CoFe₂O₄ photocatalyst was characterised by XRD, SEM, SEM Mapping, TEM, XPS, and BET-surface area analysis. The TEM image reveals cubic shapes with an average size of 10-20 nm. The surface area of the CoFe₂O₄ NPs was found to be 16.42 m² g-1. The photocatalytic activity of CoFe₂O₄ has proved to be an excellent photocatalyt for degradation of metronidazole and organic dyes such as methylene blue (MB) and rhodamine B (RhB). The rate of the reaction was found to be 0.102, 0.198 and 0.213 min-1 for metronidazole, MB and RhB respectively. The catalyst also proved to be noteworthy as it does not loss in its catalytic activity even after five cycles of reuse.
