Structural characteristics of Zn-MOFs and derived zinc oxide by X-ray diffraction peak analysis fabricated by mechanical and hydrothermal methods
In this work, the Zn based MOFs were synthesized from cyanoguanidine and zinc acetate source precursors via two hydrothermal methods and high energy ball milling technique and also the free salt and bimetallic samples have been synthesized. Then, the fabricated Zn-MOFs were heat for calcination at 5...

| description | In this work, the Zn based MOFs were synthesized from cyanoguanidine and zinc acetate source precursors via two hydrothermal methods and high energy ball milling technique and also the free salt and bimetallic samples have been synthesized. Then, the fabricated Zn-MOFs were heat for calcination at 550 °C for 110 min. The synthesized nanostructures were examined by XRD, SEM and FTIR analysis to gain insight about structure, morphology and functional groups properties. The results confirm that it is possible to prepare Zn MOFs using high energy ball milling methods. Besides, the fabricated MOF and complex structures can be converted to porous zinc oxide (ZnO) by a simple thermal annealing in air. Then, the line broadening of ZnO from mechanochemical and hydrothermal methods was showed due to the small crystallite size and lattice strain. The broadening was studied by the Scherrer formula and Williamson Hall (UDM, USDM, UDEDM) and Size-strain plot techniques. In addition, undesirable phases may affect the synthesized part during thermal cycles. We demonstrate the potential of using high-energy X-ray diffraction for detailed analysis of minority phases in ZnO-derived components. |
