Annealing Temperature Effects in Co-Precipitated CoFe₂O₄ Nanoparticles Using Bengawan Solo River Fine Sediment

Abstract:

In this study, the synthesis of CoFe₂O₄ by using the fine sediment of the Bengawan Solo River, Trucuk District, Bodjonegoro Regency as raw materials with the coprecipitation method has been successfully carried out. The fine sediment is used as a source of Fe cation in the synthesis of CoFe₂O₄. The XRD confirmation results showed that CoFe₂O₄ is formed at an annealing temperature of 800° C with crystallite sizes ranging from 34.88 to 38.05 nm. Thus, the VSM characterization showed that the magnetic properties of the CoFe₂O₄ nanoparticles depend on the heat treatment of the fine sediments as ore materials. Finally, the obtained CoFe₂O₄ samples can be used as photocatalysts with a maximum reduction rate ratio of 83%.
