Abstract: Applications of metal-organic frameworks. Metal organic frameworks (MOFs) as exciting type of organic/inorganic hybrid materials have attracted great focus of scientists in the last two decades. The objective of this study was to synthesize Ce-UiO-66 and its inorganic hybrids (CdS/Ce-UiO-66/Ag3PO4) and characterize the synthesize cerium metal organic frameworks (Ce-UiO-66) and its inorganic hybrids. All the materials in this work were prepared via hydrothermal synthesis and characterized by X-ray powder diffraction (XRD) and scanning electron microscope (SEM) hyphenated with energy dispersive x-ray (EDX). From XRD data, peaks at 28.2, 29, 46.7 and 48.7 suggests the occurrence of CeO2. The three typical diffraction peaks observe at 2θ values of 26.67, 44.00 and 52.05 corresponding to miller indices of (100), (202) and (311) could be ascribed to the hawleyite structure of CdS. For the (1:1) ratio of CdS to Ce-Uio-66/Ag3PO4 the XRD result reveal that the MOF structure disappeared making it more amorphous when compare to the other ratios. As the result, no diffraction peak attributable to Ag3PO4 was observed. The scanning electron microscope (SEM) hyphenated with energy dispersive x-ray (EDX) analysis for all the inorganic hybrids raveal that all the distinct morphologies shown in their single phase vanished upon composite formation evidencing the well mix of each components. The EDX spectra in all cases show the presence of each component in the ternary system. Generally, in this research we focus on the synthesis of Ce-MOF and its inorganic hybrids and characterizations were studied. All the as-synthesized materials fall in the nanoscale.
