Tailored synthesis of CuS nanodisks from a new macrocyclic precursor and their efficient catalytic properties on methylene blue dye degradation

摘要: In this study, CuS nanodisks have been synthesized from a tetraaza (N4) macrocyclic complex precursor by facile wet chemical method. The crystallinity and morphology of the as-synthesized products were characterized X-ray diffraction transmission electron microscopy, which confirm phase pure crystalline nanostructures with ~15 to 20 nm in dimension ~5 nm thickness. A possible formation mechanism growth process are discussed using thiourea ligand as sulfur donor stabilizing agent, respectively. Cyclic N4 also acts binding agent template-guide oriented nanodisks. optimized geometry ligands complexes was calculated B3YLP functional, indicates that HOMO located on metal center N atoms weakly bonded center. catalytic activity toward MB degradation light displays higher rate than under dark presence H2O2.
