CsPbI3 perovskite nanostructures fabricated via the hydrothermal method. The effect of various parameters such as molar ratios of precursors, different types of capping agents, reaction time and temperature investigated on purity, morphology and particle size of nanostructures. The purity of as-fabricated products confirmed by X-ray diffraction (XRD), X-ray energy dispersive spectroscopy (EDS). The particle size and uniformity of the products characterized by field emission scanning electron microscopy (FESEM). This is the first effort on the investigation of photocatalytic behavior of the CsPbI3 nanostructures. The photocatalytic performances for destruction of organic dye under UV light studied and indicated these nanoparticles could remove and degrade rhodamine B about 76.9%. The results showed that the CsPbI3 perovskite nanostructures can be used as high-performance catalysts for water pollution removal
