Synergistic Effect of Dual-Doped Carbon on MoC Nanocrystals Facilitates Alkaline Hydrogen Evolution.

Abstract in brief

• The study explores how dual doping with boron (B) and nitrogen (N) on a carbon layer surrounding MoC nanocrystals improves their ability to catalyze hydrogen evolution in alkaline solutions by adjusting hydrogen and water adsorption properties.
• The B and N dual-doped carbon layer enhances electronic interactions with MoC, resulting in lower energy barriers for hydrogen release and water splitting, leading to high catalytic efficiency.
• The resulting MoC-based catalyst outperforms commercial platinum on carbon (Pt/C) in terms of activity and cost, demonstrating its potential for large-scale, noble-metal-free water splitting applications.]
