Özet

The production of nanomaterials from new sources is an important topic because the diversity of the raw materials provides a variety of properties for these materials, therefore, this study involved the synthesis and characterization of a zinc complex obtained by reacting 2,6-dimethoxybenzoic acid (DMB) with zinc chloride in the presence of triethylamine as a bulk base. The structure and coordination mode of the resulting zinc complex were determined through various techniques, including FTIR, 1H NMR, elemental analysis, and molar conductivity. The findings confirmed that the 2,6-dimethoxybenzoic acid ligand acts as a bidentate ligand, coordinating through both oxygen atoms of the carboxylic group, resulting in a complex of the type [Zn(DMB)Cl]2. This complex was then used as a precursor for the synthesis of a ZnO-MWCNTs nanocomposite using ultrasound waves. The synthesized nanocomposite was characterized using SEM and XRD techniques. The results revealed the formation of small spherical clusters around the carbon nanotubes, with an average size of the spherical nanostructures measuring 11.875 nm. Moreover, the incorporation of zinc oxide nanoparticles had a positive impact on increasing the diameter of the carbon nanotubes from 3.005 nm to 21.218 nm.
