|제목||Study of Visible-light Responsive Reusable Photocatalyst|
|초록|| Pure semiconductor photocatalyst works in the UV region. Heterostructures are well known to reduce the bandgap energy of semiconductors. Fe3O4@TiO2-Au structure is easy to reuse because it can be easily separated after use due to the strong magnetism of Fe3O4. In addition, the addition of TiO2 and Au to Fe3O4 nanoparticles reduces the bandgap energy, which enables catalysis in the visible region.
In this study we fabricated Fe3O4@TiO2-Au microsphere. The properties of Fe3O4@TiO2-Au microsphere were investigated by TEM, EDX, XRD and XPS. The degradation of methyl orange (MO) was observed using UV-Vis and Raman spectroscopy. Details on its characterization and analysis will be discussed in this presentation.
