“…[1][2] For example, MnFe(P, As) is a promising material in the field of magnetic refrigeration due to its large magnetic entropy change; [3][4] phosphorous-rich transition metal phosphides such as Cu 3 P, NiP 2 , and FeP are promising alternatives to conventional negative lithium-ion battery electrodes due to their highly reversible capacities and good cyclabilities compared with carbon-based compounds, oxides or intermetallics; 5-7 metal-rich phosphides have also been demonstrated to be responsible for improved conductivity of lithium-ion battery; 8 Ni 2 P is one of the most active catalysts for hydrodesulfurization and hydrodenitrogenation. [9][10] Previous work on phosphides was focused on main group metal (e.g., Ga, Al).…”

We have synthesized anisotropic nickel phosphide nanocrystals, including triangular/hexagonal nanoplatelets, nanorods and nanowires, via a solution-phase synthetic method that uses nickel(II) acetylacetonate as a metal precursor and trioctylphosphine as a phosphorus source. Nickel phosphide nanoplatelets have been prepared from a one-pot reaction, and their dimensions in the length mostly vary from 20 to 50 nm, while their thicknesses are in a narrow range of 7-9 nm. Nickel phosphide nanorods with a width of approximately 6 nm and a typical length of 25-32 nm can be synthesized from either the one-pot reaction or the multi-injection approach, although the latter can generate nanorods with a much higher uniformity. A continuous injection approach has been used to synthesize nanowires that have a typical width of approximately 6 nm and a length ranging from tens of nanometers up to several hundred nanometers. Major factors that influence the growth of nickel phosphide nanocrystals have been investigated, and a multi-surfactant system is found to be essential for the formation of anisotropic nanostructure. Magnetic studies have revealed paramagnetic characteristics for all the synthesized samples.

“…These structures are strongly related to each other and have two common polyhedra, which form the coordination of metal atoms in tetrahedral and square-pyramidal sites. Recently, research interests were renewed in MnFeAs x P 1Àx compounds since the discovery of the large room temperature magnetocaloric effects (MCE) in hexagonal Fe 2 P-type structures [8][9][10][11]. The large MCE originates from the occurrence of a first order magnetic transition near the Curie temperature T C , accompanying with a large, discontinuous and anisotropic lattice distortion.…”
