A hydrothermal method for low-temperature growth of nanocrystalline pyrite nickel diselenide

Reaction of a selenium alkaline solution with a nickel complex aqueous solution produces nanocrystalline pyrite NiSe 2 with an average particle size of about 20 nm in the temperature range of 90–100°C through a hydrothermal method. X-ray diffraction analysis indicates that the product is a single ph...

Description
Summary:Reaction of a selenium alkaline solution with a nickel complex aqueous solution produces nanocrystalline pyrite NiSe 2 with an average particle size of about 20 nm in the temperature range of 90–100°C through a hydrothermal method. X-ray diffraction analysis indicates that the product is a single phase of pyrite nickel diselenide. TEM and ED images show that the product has a good crystallinity with a plate-like form. The synthesis can be performed conveniently and safely.
