Recently, water pollution caused by dyes and organic pollutants (such as methyl orange and methylene blue) has been produced through industrial textiles, leather, pharmacy, etc., which has become a serious ecological issue. [1][2][3] Consequently, several technologies, such as chemical precipitation, adsorption, and membrane, have been applied to treat these toxic organic contaminants from water. 4-6 Among these used methods, photocatalysis has attracted extensive attention due to the unique advantages such as low energy consumption, easy fabrication, repeatable process, high removal efficiency, and limited chemical requirement. 7 In the photocatalysis process, sunlight is used as a source of energy; the process begins with absorbing a photon and continues by generating electrons and holes. The electron and holes pairs react with oxygen, water, and produce active radicals, which could destroy organic pollution in water. 8,9 That is

In the present study, TlCdI nanostructures were synthesized via a facile sonochemical method. The effect of molar ratio of TlI to CdI, reaction time, power of sonication, and the capping agents was investigated on morphology, size, and purity of the products. The as-prepared nanomaterials were characterized by X-ray diffraction, X-ray energy dispersive spectroscopy, field emission scanning, transmission electron microscopy, and Raman spectroscopy. The optical property of TlCdI nanoparticles was investigated by ultraviolet-visible spectroscopy (UV-vis), and the band gap was estimated about 2.82 eV. The photocatalytic behaviors of the nanoparticles were investigated by removal and degradation of different organic dyes under the UV irradiation. The results indicated a highest degradation for acid black 1 of 85.7% in 110 min. This sample was selected as an optimum sample for photocatalytic application.
