Abstract

Abstract: A series of multi-walled carbon nanotubes (MWCNTs)-loaded Bi2 S3 nanomaterials composites (MWCNTs/Bi2 S3 ) were prepared by hydrothermal method. The crystallization, morphology and other properties of the obtained MWCNTs/Bi2 S3 composites were completely characterized by powder X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transformed infrared spectroscopy (FT-IR), Thermal gravimetric analysis and differential thermal analysis (DTA-TG), N2 adsorption-desorption isotherm, and UV–vis diffuse reflectance spectroscopy (DRS). In this work, the photocatalytic activity of the as-prepared materials was evaluated for methylene blue (MB) degradation under visible light irradiation. Comparing with others work, the composites showed excellent photocatalytic performance and maintained a good stability during the constant cycling experiment. Finally, a possible photocatalytic reaction mechanism on the MWCNTs/Bi2 S3 composites was proposed.
