Abstract

Abstract:

Homogeneous ZnO/In₂O₃heteronanostructure photocatalytic materials were successfully synthesized by a pyrohydrolytic method. The structures and morphologies of ZnO/In₂O₃heterostructure were investigated by field emission scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). Results indicate that ZnO/In₂O₃ heterostructures consist of hexagon nanosheet ZnO with diameter of about 200-300 nm and thickness of 40-60 nm decorated with In₂O₃ nanoparticles. Compared with the degradation efficiency of RhB by pure ZnO, pure In₂O₃ and ZnO/In₂O₃, the results show that ZnO/In₂O₃heterostructure photocatalysts possess higher photocatalytic efficiency. The enhanced photocatalytic activity is mainly attributed to the role of narrow-band semiconductor In₂O₃, which could effectively absorb visible light. Photo-excited electrons of In₂O₃’senergy band remove to conduction band of ZnO, while photo-excited holes still remain in In₂O₃’s valence band, which contributes to the separation of photo-generated electrons and holes, decreases recombination probability, and thus improves the photocatalytic efficiency.

Key words: ZnO, ZnO/In₂O₃, RhB, photocatalytic efficiency
