| description | The synthesis and design of low-cost visible-light-active catalysts for the photodegradation of organic dyes have been regarded as an efficient way to use solar energy in addressing environmental issues. We report the fabrication of MoS<sub>2</sub>/CdS nanoparticles functionalized with Bi<sub>2</sub>S<sub>3</sub> nanoflakes. The ternary composites of “MoS<sub>2</sub>/CdS/Bi<sub>2</sub>S<sub>3</sub>” were synthesized in situ by a hydrothermal method at different temperatures. The changes in structural, optical, and morphological properties of the synthesized CdS/MoS<sub>2</sub>/Bi<sub>2</sub>S<sub>3</sub> were explored. The effects of Bi<sub>2</sub>S<sub>3</sub> on CdS/MoS<sub>2</sub> were thoroughly studied by performing an X-ray diffractometer (XRD), a scanning electron microscope (SEM), an ultra-violet–visible spectrometer (Uv–vis), and Fourier transform infrared spectroscopic (FT-IR) studies of the nanoparticles. XRD confirms the cubical crystal structure of the nanoparticles. SEM studies possess the modulation in the surface morphology with the tenability in volume ratios of “MoS<sub>2</sub>/CdS/Bi<sub>2</sub>S<sub>3</sub>” composites. It was observed that the bandgaps calculated using absorption measurements could be manipulated from 2.40 eV to 0.97 eV with varying Bi<sub>2</sub>S<sub>3</sub> in the MoS<sub>2</sub>/CdS nanostructures. FT-IR confirmed the synthesis of “MoS<sub>2</sub>/CdS/Bi<sub>2</sub>S<sub>3</sub>” nanoparticles. On allowing the visible light to fall for 120 min, it was observed that “MoS<sub>2</sub>/CdS/Bi<sub>2</sub>S<sub>3</sub>” degrades the methylene blue up to 90%. The calculated results of “MoS<sub>2</sub>/CdS/Bi<sub>2</sub>S<sub>3</sub>” suggest that the synthesized material could be a strong candidate for photodegradation applications. This research work explains the synthesis of MoS<sub>2</sub>/CdS/Bi<sub>2</sub>S<sub>3</sub>-based nanocomposites for the degradation of dye using a photocatalytic process. The final results show that this catalyst effectively degrades the dye. |
