Synthesis of novel, efficient, highly porous nanocomposite metal-organic framework UiO-۶۶-COOH functionalized with nitrogen-rich heterocyclic compounds aimed multifunctional biological applications

In this study, the novel, efficient, and well-built structure of UiO-۶۶-COOH@APTMS@Aminotetrazoles@Au-NPs outlined as a heterogeneous catalyst aimed to occur multifunctional biological applications. The products of porous nanocomposite metal-organic framework UiO-۶۶-COOH coated with nitrogen-rich heterocyclic compounds and natural compounds were obtained with a high yield percentage, well-designed. Obviously, electrostatic interaction of Gold-Nanoparticles with the junctions is strong enough to hold metal ions, so Au is effectively stabilized with high stability. Eventually, this functionalized nanocomposite metal organic framework Au complex can effectively prevent Au leaching, which is attributed to the existing joints. Also, analysis of the recycled catalyst was performed after each reuse cycle to evaluate the amount of Pd leaching. In addition, the Pd elution determined by ICP analysis after nine (۹) recycles was negligible. This research is motivated by excellent results, tried to evaluate and ability to fully measure and identify the newly synthesized MOF-Catalyst as UiO-۶۶-COOH@Aminopropylthrimethoxysilane@Aminotetrazole@Au-NPs using UiO-۶۶-COOH by cross-linking of Aminopropylthrimethoxysilane, tetrazoles, ۵-Aminotetrazole and stabilization of Au-nanoparticles on the above substrate to form a highly efficient and new green MOF-catalyst UiO-۶۶-COOH@APTMS@Aminotetrazoles@Au-NPs used as a heterogeneous catalyst for promoting multifunctional biological applications. The new synthesized heterogeneous catalyst was studied, identified and investigated using the analysis of various analyzes including XRD, FT-IR, TEM, FE-SEM, EDS-Mapping and ICP. In this research, structural properties, synthesis methods, post-synthetic modification, challenging nano-catalysts with unique structures containing metal-organic frameworks on metal-organic frameworks are investigated in various fields. One of the most challenging aspects of structural engineering in the field of nanocomposites and porous catalysts is the creation of polymer couplings, alloys/MOF compounds. Also, due to the special and unique structure of metal-organic frameworks on metal-organic frameworks, affordability, porosity and particularly high cross-sectional area and suitable biocompatibility, polymeric metal-organic framework composites stabilized with noble metal nanoparticles, including high-yield gold, can be used for applications in the field of biology.
