In this research, HgI2 nanostructure was created through a novel simple approach. The influence of some preparation factors was examined to reach optimum condition. Findings of this work demonstrated that shape and size of the HgI2could be remarkably influenced by these factors. The as-fabricated HgI2 nanostructure was characterized by FT-IR, FESEM, EDS and XRD. According to the obtained results, it was found that with the aid of this new approach can be produced uniform sphere-like HgI2 nanostructure. The photocatalyst capability of as-obtained HgI2 nanostructure was also evaluated by degradation of the organic contamination under ultraviolet light illumination.
