Preparation of thallium nanomaterials from thallium(I) coordination polymers precursors synthesized by green sonochemical and mechanochemical processes

Microstructures of [Tl₂(μ₂-ATA)]_n (1), [HATA=2-aminoterephthalic acid], supramolecular polymer was synthesized by sonochemical process (1S) and used as new precursor for preparation pure phase of thallium(III) oxide microstructures. [Tl(μ₂-dcpa)]_n (2), [Hdcpa=2,4-dichlorophenoxyacetic acid], is another supramolecular polymer which was synthesized by green sonochemical (2S) and mechanochemical (2M) processes. These two samples of 2 were also used for preparation of thallium nanomaterials. Both processes on 2 were successful but mixture of Tl, Tl₂O₃ and TlCl nanostructures with various morphologies from 2S and mixture of Tl₂O₃ and TlCl nanoparticles from 2M were obtained. These micro and nanostructures were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM).
