Synthesis and characterization of a nickel selenide series via a hydrothermal process

Nickel selenides (NiSe and NiSe2) were successfully produced by hydrothermal method using CTAB as surfactant and hydrazine as reductant. It was found that the molar ratio between NiCl2⋅6H2O and SeCl4 have played important role in controlling the composition, structure and morphology of products.
