Expertise engineering of ternary Bi2S3/FeWO4/CoS2 nanocomposites for enhanced dye degradation towards environmental application
The design and fabrication of effective nano composites for organic pollutant degradation is a promising strategy for advancing environmental remediation. In this regard, semiconductor-based photocatalysis has emerged as a viable approach to environmental cleanup. The ternary Bi<sub>2</sub>S<sub>3</sub>/FeWO<sub>4</sub>/CoS<sub>2</sub>nanocomposite was synthesized via a one-step hydrothermal process. The prepared nanocomposite was characterized using various analytical techniques, including XRD, FTIR, SEM, EDX, TEM, XPS, and UV-DRS spectroscopy. The as-prepared Bi<sub>2</sub>S<sub>3</sub>/FeWO<sub>4</sub>/CoS<sub>2</sub> nanocomposite exhibited a higher degradation efficiency of 97.1% for MB aqueous dye solutions under visible light irradiation. According to the results of the radical trapping experiment, OH<sup>•</sup> radicals are the main radicals for the degradation of MB. A potential photocatalytic mechanism for Bi<sub>2</sub>S<sub>3</sub>/FeWO<sub>4</sub>/CoS<sub>2 </sub>nanocomposite was proposed. These results exhibited that the synthesized nanocomposites are a potential candidate for the organic pollutant degradation and environmental remediation.
