Solvothermal synthesis and characterization of Ni doped MOF-5

Partial isomorphic substitution of Zn in MOF-5metal clusters by nickel ions is described in the paper. Ni(II) ions have been incorporated during solvothermal crystallization into the Zn based MOF-5 framework, which is one of the most studied MOF materials. MOF-5 is moisture sensitive even under atmospheric conditions.Ni-doped MOF-5was successfully synthesized via solvothermal crystallization process with ratio Zn/Ni almost 1:1to enhance the hydrostability of MOF-5.Applying characterization techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX) strongly support the effective incorporation of Ni into the MOF framework.
