A novel bi-functional two-dimensional nanocomposite, referred to as BF-2D-ZnO@Tl-based MOF-NC, has been developed. This material was synthesized via a one-pot approach using 1,3,5-benzenetricarboxylic acid, an organic ligand not previously employed in Tl-based MOF synthesis, along with thallium nitrate as the metal source and double-distilled water as the solvent. This specific type of thallium-containing metal-organic framework has not been explored before. Uniform growth of ZnO nanoparticles (ZnO NP) was achieved on the surface of the functionalized ultrathin 2D Tl-based MOF layers. The synthesized hybrid nanocomposites underwent characterization using XRD, SEM, EDS, VSM, TGA, and BET analysis. XRD results indicated the presence of highly crystalline structures. SEM morphological studies corroborated the successful formation of two-dimensional nanostructures, while elemental and thermal analyses confirmed adequate chemical bonding and compositing between the parent materials. Nitrogen adsorption-desorption measurements revealed a significantly larger cumulative pore volume (0.360 cm³/g) for the BF-2D-ZnO@Tl-based MOF-NC hybrid nanocomposite compared to its individual components, Tl-based MOF and ZnO NP (both 0.030 cm³/g), suggesting promising potential for various applications.
