Controllable synthesis of molybdenum-based electrocatalysts for a hydrogen evolution reaction

Carbon sphere supported MoO₂, MoC and Mo₂C materials have been synthesized via a simple two-step method. Mo₂C/C exhibits a superior electrocatalytic performance and stability for the HER in both acid and basic media due to its excellent crystal structure, enlarged surface area, high electronic conductivity and ultra-small particle size.
