Abstract:

Article Preview

Zinc sulfide nanoparticles as undoped and doped with nickel have been prepared by the reaction of Zn(CH3COO)2 and Ni(CH3COO)2 with potassium O-ethyldithiocarbonate (ethyl xanthate, C2H5OCS2k) at 80 in N, N - dimethylformamide (DMF) solution for 24 h. The structures of the products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), and their optical properties were studied by UV-Vis spectroscopy. The photocatalytic experiment by degrading methyl orange in aqueous solution under UV light indicated that the degradation efficiency of Ni (6%)-doped ZnS nanoparticles increased to 75% with comparison to 43% of degradation efficiency for undoped ZnS nanoparticles.
