Solvo-thermal synthesis of crystalline dinickel phosphide

Abstract Nanocrystalline dinickel phosphide was synthesized via a solvo-thermal route using PCl 3 and NiCl 2 as precursors, and Na as reductant. The crystals were characterized by X-ray powder diffraction and transmission electronic microscopy. It was shown that the product is pure Ni 2 P which crystallizes very well with an average size of about 80 nm.
