solid state synthesis of nio nanoparticles from [(1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii)] chloride

in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligand 1,2-bis(2-formyl-3-methoxyphenyl)propane. the structure and morphology of nio nanoparticles are characterized by fourier transform infrared spectroscopy (ft-ir), powder x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). xrd and tem analysis show that nio nanoparticles have pure and cubic phase with the average size of 5-10 nm.
