Analysis of Gaseous Fuel Adsorption by Synthesizing Zinc-BDC MOF and Cerium-BDC MOF

In terms of novel porous materials for fuel adsorption, metal–organic frameworks (MOFs) are thought to have promise. The storage of gaseous fuels utilizing adsorption was examined through a research of material production, analysis, and nitrogen adsorption. Two MOF samples one is zinc—benzene-1, 4-dicarboxylic acid MOF and cerium—benzene-1, 4-dicarboxylic acid MOF were created utilizing benzene-1, 4-dicarboxylic acid as the solvent. Each MOF has demonstrated a distinct phase structure and chemical composition, as well as various pore textural characteristics and nitrogen adsorption capacities. The quality of the synthesized MOFs is validated after testing using X-ray diffraction analysis and scanning electron microscopy—energy-dispersive X-ray spectroscopy analysis, which reveal the structure of the MOFs. Zinc—benzene-1, 4-dicarboxylic acid MOF has a surface area of 3.5118 m2/g, whereas cerium—benzene-1, 4-dicarboxylic acid MOF has a surface area of 74.6374 m2/g. Zinc—benzene-1, 4-dicarboxylic acid MOF has a pore size of 35.0327 nm, whereas cerium—benzen-1, 4-dicarboxylic acid MOF has a pore size of 54.8678 nm. In contrast to the cerium—benzene-1, 4-dicarboxylic acid MOF, which is macroporous, the zinc—benzen-1, 4-dicarboxylic acid MOF is mesoporous. Therefore, two MOF adsorbents that can absorb gaseous fuels are created.
