概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
The investigation concentrated on verifying the existence of zinc
(Zn) in the MOF-525 zirconium (Zr) framework. Zr and Zn were found by looking
at the typical peaks in the X-ray Diffraction (XRD) pattern. By means of
further investigation of these peaks, the Zr: Zn ratio inside the produced
material could be ascertained, therefore offering vital data on the composition
and possible doping degree of Zn in the MOF structure. This is important since
the addition of secondary metals such as Zn can dramatically change the
characteristics of MOFs including stability, spin properties, and gas
adsorption capacity.
実験 / Experimental
MOF-525(Zn) was synthesized through an approach using a mixed linker system and characterized using XPS.
結果と考察 / Results and Discussion
Further
study of these peaks allows one to determine the Zr:Zn ratio inside the
generated material, therefore providing essential information on the
composition and possible doping degree of Zn in the MOF structure. Beyond the
metallic elements, carbon (C), nitrogen (N), and oxygen (O) were quantified by
extensive elemental analysis. These components define the porosity and
functioning of the MOF-525 structure and constitute the natural linkers within
its construction. By means of exact ratios of C, N, and O, one guarantees the
effective synthesis of the intended MOF structure and aids in the comprehension
of any possible flaws or non spontaneous spin interactions. Variations from the
intended elemental composition may point to problems during synthesis or the
existence of contaminants.
Combining the other characterizations for metal identification and ratio
calculation with bulk elemental analysis this all-encompassing method offers a
complete knowledge of the MOF- 525(Zn)material. Linking the structure and
composition of the material with its performance in spintronics. Techniques
including X-ray Photoelectron Spectroscopy (XPS) to probe the oxidation states
and chemical environment of Zn inside the MOF framework for spatial distribution of Zn within the MOF particles could be used in further
investigations.
