Synergistic Effect of Nitrogen/Phosphorus Co-Doping and Molybdenum Carbide Induced Electron Redistribution of Carbon Layer to Boost Hydrogen Evolution Reaction?

The development of highly efficient non-precious-metal-based electrocatalysts for the hydrogen evolution reaction is imperative for promoting the large-scale application of electrochemical water splitting.Herein,nitrogen/phosphorus co-doped carbon nanorods encapsulated Mo2C nanoparticles(Mo2C@PNC)have been prepared by pre-phosphating treatment in combination of the coordina-tion with polydopamine and the subsequent pyrolysis.The phosphating temperature has a significant effect on the content of phos-phorus within the resultant Mo2C@PNC,and the optimal catalyst delivers superior HER activity with the low overpotential of 104 mV at a current density of 10 mA·cm-2 and good stability for 8 h,which has been theoretically demonstrated to originate from the syn-ergistic effect between P doping and Mo2C induced electron redistribution of nitrogen-doped carbon layer.
