One-Step Construction of Co2P Nanoparticles Encapsulated into N-Doped Porous Carbon Sheets for Efficient Oxygen Evolution Reaction

It is critical and challenging to develop high performance transition metal phosphides (TMPs) electrocatalysts for oxygen evolution reaction (OER) address fossil energy shortages. Herein, we report the synthesis of Co2P embedded in N-doped porous carbon (Co2P@N-C) via a facile one-step strategy. The obtained catalyst exhibits lower overpotential 352 mV OER at current density 10 mA cm−2 small Tafel slope 84.6 dec−1, with long-time reliable stability. excellent electrocatalytic Co2P@N-C can be mainly owed synergistic effect between highly conductive N-C substrate, which not only affords rich exposed active sites but also promotes faster charge transfer, thus significantly promoting process. This work presents promising industrially applicable synthetic strategy rational design nonnoble enhanced performance.
