High‐entropy carbide (HEC) is a promising alternative to precious metal catalysts for the hydrogen evolution reaction (HER). However, the preparation of nanoscale HECs is a great challenge although many methods have been developed to prepare bulk HEC materials. Herein, an electrical discharge induced bulk‐to‐nanoparticle transformation method is reported, by which well dispersed sub‐10 nm high entropy...
Nickel phosphide has been shown to be active toward hydrogen evolution reaction (HER). In this paper, we demonstrate the phase and composition controllable synthesis of nickel phosphide-based nanoparticles (NiP-based NPs) via a low-temperature phosphidation reaction (250 °C) using NaH2PO2 as the phosphorus source and the as-prepared Ni(OH)2 precursor as the nickel source. Interestingly, by changing...
