Ultrafine CoP/Co₂P Nanorods Encapsulated in Janus/Twins-type Honeycomb 3D Nitrogen-Doped Carbon Nanosheets for Efficient Hydrogen Evolution.

ABSTRACT: In this study, we report a Janus- or twins-type honeycomb 3D porous nitrogen-doped carbon (NC) nanosheet array encapsulating ultrafine CoP/Co₂P nanorods supported on Ti foil (CoP/Co₂P@NC/Ti) as a self-supported electrode for efficient hydrogen evolution. The synthesis and formation mechanism of 3D porous NC nanosheet array assembled into a honeycomb layer with ultrafine CoP/Co₂P single-crystal nanorods encapsulated is systematically presented. The CoP/Co₂P@NC/Ti electrode exhibits low overpotentials (η₁₀) of 31, 49, and 64 mV at a current density of -10 mA cm^-2 in 0.5 M H₂SO₄, 1.0 KOH, and 1.0 M PBS, respectively, exceeding the overwhelming majority of the documented transition metal phosphide-based ele
