Recently, the presence of heavy metal ions, including hexavalent chromium Cr(VI), in aqueous environments has attracted a huge amount of attention. These ions are highly toxic and can endanger the human’s health. Therefore, it is of the principal significance to find an efficient and environmentally friendly approach to remove or reduce these ions concentration in water sources. In this work, the use of a Metal-Organic Frameworks@Semiconductor (MOF@Semiconductor) structure as an efficient photocatalytic material is considered for this purpose. The structures of as prepared specimens (ZIF-8@TiO2 NPs) were characterized by X-ray diffraction pattern, FT-IR spectra, and FE-SEM images. The UV-Vis spectroscopy data analysis was also performed to determine the amount of Cr(VI) in the tested water.
