Metalphosphides from the 3d period exhibit a range of structures and compositions. Many metal-rich phosphides and monophosphides function as heterogeneous electrocatalysts in the hydrogen evolution reaction. This paper describes the direct and tin flux-assisted synthesis of phosphorus-rich metalphosphides with MP2 or MP3 compositions. The facile synthesis of FeP2, CoP3, NiP2, and CuP2 is thermochemically
Ironphosphides, FeP2 and FeP4, have been synthesized and characterized for the application to non-aqueous Na-ion battery. FeP2 shows no significant electrochemical reactivity in Na-cell. However, FeP4 composite electrode with sodium polyacrylate binder delivers a reversible capacity of 1137 mAh·g− 1 and a Coulombic efficiency of 84.0% during the first cycle under a current density of 89 mA·g− 1.
