In this article, the spinel NiCo2O4 nanosheets with diameters of 100-200 nm were prepared by calcinations of co-precipitates, which were obtained by co-precipitation method. Different kinds of precipitants, including NaOH, KOH, Na2CO3 and ethanedioic acid aqueous solutions were investigated, and regular hexagonal nanosheets are synthesized only when the precipitant is strong KOH or NaOH solution. The morphology and structure of the hexagonal precursor particles and nanosheets were investigated, and the mechanism of the formation of hexagonal nanosheets is discussed.

ZnS nanoparticles were prepared from homogeneous chemical co-precipitation reaction by using zinc acetate, sodium sulfide [Na2S] and Poly Vinyl Polypyrrolidone [PVP]. The basic, morphological, and optical properties of the synthesized nanoparticles were characterized using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Energy Dispersive X-ray Analysis (EDX) and Ultraviolet-Visible (UV-Vis) absorption. The structural and optical characterization of the samples observed by SEM, FTIR, EDX and UV-Vis spectrometer showed that ZnS nanoparticles were formed.
