Controllable synthesis of new Tl2S2O3 nanostructures via hydrothermal process; characterization and investigation photocatalytic activity for degradation of some anionic dyes

Abstract The synthesis and characterization of novel high-quality and high-yield plate-like thallium(I) thiosulfate nanostructures via simple hydrothermal method between TlNO 3 and sodium thiosulfate at relatively low temperature is reported without using any surfactant and organic solvents for the first time. The as-synthesized nanostructures were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), ultraviolet-visible (UV–vis) spectroscopy, photoluminescence (PL) spectroscopy, cyclic voltammetry (CV) and Fourier transform infrared (FT-IR) spectra. The effect of temperature and reaction time on the morphology and particle sizes Tl 2 S 2 O 3 nanostructures has been investigated. The photocatalytic activity of the synthesized products has been compared in the photodegradation activity of three anionic dyes. This effort has offered a general, simple, and effective method to control the composition and morphology of Tl 2 S 2 O 3 nanostructures in aqueous solution, which exposed potential new insight into nanostructure synthesis methodology.
