Synthesis and Photocatalytic Properties of One-Dimensional Composite Bi2O3-Bi2CrO6 Nanowires

Abstract EN

One-dimensional composite Bi2O3-Bi2CrO6 nanowires were successfully fabricated by a simple microwave-assistant hydrothermal method.

The successful fabrication of one-dimensional Bi2O3-Bi2CrO6 nanowires can only be realized at pH value range of 1–5 of the starting solution.

The fabricated nanowires were characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), UV-visible diffuse reflectance spectra (UV-Vis DRS), and photoluminescence (PL), respectively.

The diameter of the nanowires varies from 30 to 100 nm; the length is a few micrometers.

Methylene blue (MB) solutions were used to evaluate the visible light photocatalytic activities of the fabricated samples.

Compared with Bi2O3, the fabricated Bi2O3-Bi2CrO6 nanowires show enhanced efficiency in oxidization of MB under visible light.
