In this preliminary study, we have succeeded in synthesizing Fe3O4@TiO2 nanocomposite with the addition of PVP using the chemical co-precipitation method. The Fe3O4 used is derived from the synthesis of iron sand and the TiO2 is derived from the synthesis with TiCl3 as the base material using the co-precipitation method. The structural characterization of the Fe3O4@TiO2 nanocomposite studied was the effect of adding PVP on the synthesis of the Fe3O4@TiO2 core shell. Structural investigations were obtained from XRD and FTIR. The XRD results after the addition of PVP showed that there was a change in the pattern of Fe3O4 content at the peak (2θ = 35.8°) which experienced a shift and an increase in the intensity value. Changes in the pattern of TiO2 content at the peak (2θ = 25°) decreased in intensity (amorphous). These changes will affect the size of the Fe3O4@TiO2 nanocomposite structure. The results of FTIR spectroscopy showed the presence of Fe-O, Ti-O, and O-H bonds. Based on the characterization results, Fe3O4@TiO2 nanocomposite with the addition of PVP can be further developed as supporting material for optoelectronic applications. © 2023 Author(s).
