In this study, we present an approach to synthesize Tl2O3 nanoparticles using a simple co-precipitation method that leads to the formation of X-shaped particles. The sample was characterized by XRD measurements, field emission scanning electron microscopy (FESEM), diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR), and ultraviolet-visible (UV-VIS). The absorption spectrum of the sample showed that the optical band gap was 3.5 eV. The prepared photocatalyst was used in the photocatalytic degradation of Cephalexin (CPX) using irradiation, and the optimum parameters that were obtained were 0.2 g.L-1 of the photocatalyst at pH 5.5 and an irradiation time of 15 minutes. 

Graphical Abstract

X-Shaped Thallium oxide nanostructures as a high performance photocatalyst for degradation of Cephalexin


  • Thallium oxide nanopartilces were synthesized by a simple co-precipitation method and used as degradartion photocatalyst.
  • The diffraction pattern and FESEM of the prepared Tl2O3 nanoparticles showed the X-shaped morphology.
  • Cephalexin (CPX) has been degradated upto 97% after 15 min in the presence of Tl2Ophotocatalyst.
