Synthesis, characterization of Ag-doped CdS-WO2 nanocomposite and effects of photocatalytic degradation in RhB under visible light irradiation
Summary
Researchers synthesized a silver-doped cadmium sulfide and tungsten oxide nanocomposite and tested its ability to photocatalytically degrade rhodamine B dye under visible light. Developing more efficient photocatalysts could support removal of plastic-associated dye pollutants from wastewater.
Abstract In this paper, the highly stable Ag/CdS-WO2 nanocomposite was fabricated by a facile and capping agent-free hydrothermal technique. The fabricated Ag doped CdS-WO2 nanocomposite were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and UV-vis diffuse reflectance (DRS) spectroscopy. The photocatalytic performance of synthesized photocatalysts was evaluated for the photodegradation of rhodamine B (Rh B) under visible light irradiation (VLI). The parameters used for the optimization of the photocatalyst were pH, catalyst dose, oxidant dose, and irradiation time. Based on this, a possible reaction mechanism for the enhancement of photocatalytic activity of Ag/CdS-WO2 has been proposed. Hence, we have a tendency to believe it might be a promising material that may be used for the photodegradation of organic pollutants present in wastewater.
