摘要: Abstract Three novel Cobalt salicylaldimine–urea complexes {[CoxLy(H2O)n]Clz; where, L = 1,3-bis(salicylaldehydimine)urea Schiff base; x, y = 1 or 2; n = 2 8; z = 0 2} were synthesized by one-pot solvothermal treatment of methanolic solutions urea, salicylaldehyde, and cobalt chloride at 120 °C for 3 h. Subsequently, normal spinel-type Co3O4 nanoparticles, with an average crystallite size in the range 22–38 nm, easily produced via thermal decomposition 400 °C 2 h. The compounds characterized elemental analysis, analysis (TG-DTA/DTG), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV–Vis spectroscopy, transmission electron microscopy (TEM) EI mass spectroscopy. Investigation optical properties oxide, using confirmed its semiconducting revealing two band gabs 1.42–1.50 1.83–1.95 eV.
