Synergistic Effect of Dual-Doped Carbon on Mo₂C Nanocrystals Facilitates Alkaline Hydrogen Evolution.

ABSTRACT: Molybdenum carbide (Mo₂C) materials are promising electrocatalysts with potential applications in hydrogen evolution reaction (HER) due to low cost and Pt-like electronic structures. Nevertheless, their HER activity is usually hindered by the strong hydrogen binding energy. Moreover, the lack of water-cleaving sites makes it difficult for the catalysts to work in alkaline solutions. Here, we designed and synthesized a B and N dual-doped carbon layer that encapsulated on Mo₂C nanocrystals (Mo₂C@BNC) for accelerating HER under alkaline condition. The electronic interactions between the Mo₂C nanocrystals and the multiple-doped carbon layer endow a near-zero H adsorption Gibbs free energy on the defective C atoms over the carbon shell. Meanwhile, the
