| Guide Nitrogen doped carbon nanosheets supported molybdenum carbides nanoparticles (MoxC/NCS) have been synthesized by tuning the mass ratio of melamine and ammonia molybdate. The Mo2C/NCS-10 exhibits superior electrocatalytic performance and stability for HER, which was attributed to N-doped carbon nanosheets, small particle size, mesoporous structure, and large electrochemical active surface area. |

Abstract Molybdenum carbides (MoxC)/nitrogen doped carbon nanosheets (NCS) composites are synthesized via simple mixing melamine and ammonia molybdate, followed by a high-temperature treatment. Metal carbide nanoparticles with ultra-small size (13 nm) are uniformly supported on nitrogen doped carbon nanosheets. The hydrogen evolution reaction (HER) is investigated in both 0.5 mol/L H2SO4 and 1 mol/L KOH media. Mo2C/NCS-10 (melamine/ammonia molybdate weight ratio of 10:1) exhibits excellent performance with a low overpotential of 130 mV in 0.5 mol/L H2SO4 solution and 108 mV in 1 mol/L KOH solution at the current density of 10 mA/cm2. The better electrocatalytic activity could be ascribed to Ndoped carbon nanosheets, small particle size, mesoporous structure, and large specific surface area, which could provide the large electrochemical active surface area and facilitate mass transport.
