In this study, we present a approach to synthesize Tl2O3 nanoparticles using a simple Co-precipitation method leads to the formation of particles possessing the morphology of x-shape. The sample was characterized by XRD measurements, Field emission scanning electron microscopy (FESEM), diffuse reflectance spectroscopy and X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) and ultraviolet-visible (UV–vis.). The absorption spectrum of sample show that the optical band gap was 3.5 eV. The prepared catalyst was used in the photocatalytic degradation of CPX using irradiation and the optimum parameters were obtained as: 0.2 g L-1 of the catalyst, at pH 5.5 and irradiation time of 15 min.
