Abstract:

The quest for finding an effective photocatalyst for environmental remediation and treatment strategies is attracting considerable attentions from scientists. In this study, a new hybrid material, Cu_0.5Mg_0.5Fe₂O₄-TiO₂, was designed and fabricated using coprecipitation and sol-gel approaches for degrading organic dyes in wastewater. The prepared hybrid materials were fully characterized using scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. The results revealed that the Cu_0.5Mg_0.5Fe₂O₄-TiO₂ hybrid material was successfully synthesized with average particle sizes of 40.09 nm for TiO₂ and 27.9 nm for Cu_0.5Mg_0.5Fe₂O₄. As the calculated bandgap energy of the hybrid material was approximately 2.86 eV, it could harvest photon energy in the visible region. Results indicate that the Cu_0.5Mg_0.5Fe₂O₄-TiO₂ also had reasonable magnetic properties with a saturation magnetization value of 11.2 emu/g, which is a level of making easy separation from the solution by an external magnet. The resultant Cu_0.5Mg_0.5Fe₂O₄-TiO₂ hybrid material revealed better photocatalytic performance for rhodamine B dye (consistent removal rate in the 13.96 × 10^-3 min^-1) compared with free-standing Cu_0.5Mg_0.5Fe₂O₄ and TiO₂ materials. The recyclability and photocatalytic mechanism of Cu_0.5Mg_0.5Fe₂O₄-TiO₂ are also well discussed.
