Highlights

► Zinc hydroxide nitrates (ZHNs), undoped and doped with 2–10% nickel, were synthesized by precipitation method. ► The layered ZHNs were then used to produce nanostructured, undoped and nickel-doped zinc oxides (ZOs) by hydrothermal-treatment. ► Structural investigation of ZOs showed a decrease in lattice parameters with increasing the content of the doping agent, nickel. ► Optical studies of ZOs showed a decrease in band gap with increasing content of the doping agent, nickel.

Abstract

Zinc hydroxide nitrate, an anionic exchanger layered material, undoped as well as doped with 2–10% nickel, was synthesized by using a pH-controlled precipitation method. The layered materials were then used to produce the undoped and nickel-doped zinc oxides by hydrothermal-treatment. X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy confirmed the formation of pure phase undoped and nickel-doped layered materials, as well as the products of the hydrothermal-treated materials, nanostructured zinc oxides. Optical studies of the nanostructured zinc oxides showed a decrease in band gap with increasing content of the doping agent, nickel.
