In this work, we show the sorbitol-assisted synthesis method to produce polycrystalline Ni/NiO systems with different phase proportions. The samples were prepared from heat treatment of an aqueous solution of nickel chloride and sorbitol by using a s

Polycrystalline NiMn2O4 samples were synthesized by sol-gel method at 500 °C (S500), 700 °C (S700), and 800 °C (S800). The three samples were then structurally characterized by X-ray diffraction and Rietveld refinement. Results indicate that sampl
