Abstract Homogeneously dispersed Mo 2 C nanoparticles onto nitrogen-doped carbon nanotube - reduced graphene oxide support (Mo 2 C/CNT-RGO) were prepared by a modified urea glass route. Simply heating an ethanol slurry of MoCl 5 , urea, CNT, and graphene oxide at 750 °C under nitrogen atmosphere uniformly distributed 8 nm Mo 2 C nanoparticles in the nitrogen-doped CNT-RGO support. The resultant Mo 2 C/CNT-RGO exhibited markedly improved electrochemical performance for hydrogen evolution reaction (HER) compared to similarly prepared Mo 2 C/CNT, Mo 2 C/RGO, and bare Mo 2 C. Enhanced Mo 2 C/CNT-RGO performance could originate from the synergy between Mo 2 C nanoparticles with high HER activity and N-doped CNT-RGO support providing large surface area and high electrical conductivity.
