Bifunctional porous iron phosphide/carbon nanostructure enabled high-performance sodium-ion battery and hydrogen evolution reaction

Unique three-dimensional iron phosphide/carbon nanocubes are synthesized via phosphorization of Metal-Organic Framework (MOF) and exhibits significant improvement in electrochemical performance such as sodium-ion anode materials (SIBs) and hydrogen evolution catalyst (HER). The SIBs charge/discharge mechanisms are revealed via ex-situ investigations. This study demonstrates the use of MOF-derivative in realizing the potential of performance of FeP-based materials as SIBs and HER catalysts.234
