In the current research, cesium mercury tetraiodide (Cs2HgI4) nanostructures have been fabricated successfully by a simple and cost-effective sonochemical technique. The influence of varied factors such as CsI: HgI2 molar ratio, variety of surfactant, time and power of ultrasound were studied on purity, morphology, and size of samples. The as-fabricated samples were identified by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and X-ray energy dispersive spectroscopy (EDS) analysis. Cs2HgI4 nanostructures were used as a catalyst for the destruction of organic dye (methyl orange) under UV light, and degrade methyl orange about 84.3%, for the first time. The result indicated these nanoparticles can be used as high-performance catalysts for water pollution removal.
