MoS2 with Controlled Thickness for Electrocatalytic Hydrogen Evolution

Molybdenum disulfide (MoS 2 ) has moderate hydrogen adsorption free energy, making it an excellent alternative to replace noble metals as hydrogen evolution reaction (HER) catalysts. The thickness of MoS 2 can affect its energy band structure and interface engineering, which are the avenue way to adjust HER performance. In this work, MoS 2 films with different thicknesses were directly grown on the glassy carbon (GC) substrate by atomic layer...
