Resumo
We investigate the structural, morphological, chemical, and magnetic properties of Ni–NiO nanocomposites synthesized through two distinct routes, sol–gel and coprecipitation, followed by calcination. By considering several techniques we show that the resulting nanocomposites, as well as their properties, are strongly dependent on both, synthesis method and calcination temperature. Hence, we explore the possibility of tailoring the physical properties of the nanocomposite by modifying production parameters. The results place the employed routes as a simple, low-cost candidate to the production of Ni–NiO nanocomposites, especially nickel oxide.
