Charge transfer complexation between some transition metal ions with azo Schiff base donor as a smart precursor for synthesis of nano oxides: An adsorption efficiency for treatment of Congo red dye in wastewater

This mentioned article aimed to synthesized of nanostructured CuO, Co3O4 and NiO oxides based on the thermal decomposition of precursors associated from the complexation between azo Schiff base chelate (2,2′-((1E,1′E)-hydrazine-1,2-diylidenebis(methaneylylidene))bis(4-((E)-phenyldiazenyl)phenol) (NNOO)) and metal chloride salts with 1:1 M ratio. The NNOO azo Schiff base chelate, and its Cu(II), Co(II) and Ni(II) complexes were synthesized and...
