Sažetak
A strong effect of the electrospinning conditions on NiO microstructure was noticed. Viscous solutions containing nickel nitrate, polyvinylpyrrolidone, ethanol, and H2O were prepared. Produced electrospun fibers were thermally treated. The chemical composition of the viscous solution, the time of electrospinning and calcination played a crucial role in the formation of corresponding nickel oxide (NiO) microstructures. At a lower nickel nitrate concentration a porous microstructure consisting of interconnected fibers was obtained, whereas at a higher nickel nitrate concentration a laminar microstructure was obtained. The formation of metallic Ni was assigned to the reducing action of polyvinylpyrrolidone during the heating of electrospun fibers. Based on EDS and XRD analyses it was suggested that metallic Ni was restricted to the surface of NiO particles. With a prolonged heating time at increased temperature metallic Ni was reoxidized to NiO.
