Nitrogen-Plasma-Treated Continuous Monolayer MoS<sub>2</sub> for Improving Hydrogen Evolution Reaction Open
Theoretically, the edges of a MoS2 flake and S-vacancy within the lattice have nearly zero Gibbs free energy for hydrogen adsorption, which is essentially correlated to the exchange currents in hydrogen evolution reaction (HER). However, M…
