Preparation of One-dimensional ZnO/Bi2O3 Heterostructures Nanomaterial for Visible Light Photocatalysis

Abstract

We use a simple route to prepare ZnO@Bi2O3 heterostructures at room temperature by the solid-state reaction method. The paper discussed morphology and photocatalytic properties of different content of ZnO@ Bi2O3 composite nanomaterials. The as-prepared different content of ZnO@ Bi2O3 composite with different content were characterized by SEM, TEM, XRD and Uv-vis spectrometry. We find that the Bi2O3 nanoparticles are well dispersed on the ZnO Nano rods. The result shows that we can the absorption of solar light can be enhanced by coating Bi2O3 and zinc oxide /bismuth oxide sample in sunlight irradiation shows the best photocatalytic activity under sunlight irradiation
