Sonochemical synthesis of cadmium (II) Schiff base complex and its decomposition to CdO nanoparticles

A novel cadmium (II) nano complex, [Cd(EtOH)(HL)(NO3)]2 (1), (H2L = 2-[(2-Hydroxy-propylimino)-methyl]-6-methoxy-phenol) was synthesized by sonochemical method. The new nano-structure was characterized by scanning electron microscopy (SEM), X-ray powder diffraction, Fourier transform infrared spectroscopy (FT-IR) and UV-Vis spectroscopy. The thermal stability of nano complex 1 was analyzed by thermal gravimetric analysis (TGA). Furthermore, the effect of the initial substrates concentration on size and morphology of compound 1 nanostructure was investigated as well in sonochemical method. After solid-state transformation of compound 1 at 650 °C in air, pure phase nanosized cadmium (II) oxide was produced. The morphology and size of the prepared CdO samples were further observed using SEM
