Preparation of Cu₂O/TiO₂ Heterostructure with High Visible-Light Photocatalytic Activity

Abstract:

The Cu₂O/TiO₂ heterostructure nanocomposites photocatalysts with different molar ratios of Cu²⁺/Ti⁴⁺ were successfully synthesized by a simple hydrothermal procedure. The obtained samples were characterized by XRD, SEM, UV-vis DRS in order to detect the composition, the shape and the property. The photocatalytic activity of Cu₂O/TiO₂ nanocomposites was evaluated by the degradation of methyl orange (MO) as a model compound. The experimental results showed that the prepared Cu₂O/TiO₂ nanocomposites exhibited higher photocatalytic activity for the degradation of MO than the pure Cu₂O and the commercial anatase TiO₂ under visible light irradiation.
