A simple method to synthesize NiO fibers

摘要

Nickel oxide fibers with diameters 1-2 mum and lengths up to 100 mum were synthesized by a simple pyrolytic decomposition method in NaCl flux with NiSO4 as precursor. X-Ray diffraction, X-ray photoelectron spectrum (XPS) and scanning electron microscopy (SEM) techniques were used to characterize these fibers. They have single-crystal structure, large aspect ratios and macroscopic quantity. Suitable precursor and molten NaCl environment are conjectured to be key factors in this method.
