| Abstract: |
| Transition metal phosphides have drawn considerable attention as potential catalaysts for electrochemical evolution of hydrogen and oxygen. In this work, we present the synthesis and characterization of of FeP/Pt nanocomposite as a novel electrocatalyst for hydrogen evolution reaction (HER). The nanocomposite was prepared by a hydrothermal approach followed by a solid-state phosphidation at 300 °C. SEM and elemental mapping revealed that the synthesized FeP/Pt consists of coral-like FeP structures uniformly covered with Pt nanoparticles. The HER activity of the electrocatalyst was examined by linear sweep voltammetry. The FeP/Pt-modified glassy carbon electrode exhibited an overpotential of 326 mV (at a current density of −10 mA/cm2) and a Tafel slope of 128.3 mV/decade in acidic medium, while an overpotential of 390 mV (at a current density of −10 mA/cm2) and a Tafel slope of 157.1 mV/decade were obtained in alkaline medium |
