Indexing PXRD Structural Parameters of Graphene Oxide-Doped Metal-Organic Frameworks

Abstract

A family of metal-organic framework, [Mg3O3(CO2)3]∞ nanocrystallites which are also known as Mg-MOF-74, were synthesized by solvothermal method at high temperature under autogenous pressure. The graphene oxide was embedded into the framework via in-situ synthesis method to form a composite structure of Mg-MOF-74@nGO. n was varied from 0.1 to 0.6 wt% of the weight of pristine material. The synthesized samples were examined under Powder X-Ray Diffraction analysis to affirm their crystalline structure. Further studies were conducted by indexing the lattice parameters of the hexagonal crystals. The volume of unit cell and Scherrer’s crystallite size were also determined to study the effect of GO loading amount on their grown dimensions. The results showed that the presence of GO in the range of 0.1-0.6 wt% did not influence the dimension of the crystal except a slight expansion in vertical direction with the increment of GO loading.

Metal–Organic Frameworks (MOFs) Containing Adsorbents for Carbon Capture

“…Mt, BC, or A additives for the CuBTC slightly change the lattice parameters and the volume of the unit cell, where their increase was observed for CuBTC-A-15, CuBTC-Mt-15, and CuBTC-BC-15, but relatively larger biochar additives (as in CuBTC-BC-30) slightly decrease them. Similar to the study by Kamal et al [76], this could be explained by the distortion of the lattice when the composite material is incorporated into the lattice.…”

UTSA-16 has a tetragonal crystal system, and it corresponds to the space group I-42d.…”

In this study, obtained spectra matched well with the ones reported in the literature[29] and with the patterns simulated from the crystal structure data of pure UTSA-16.…”
