Abstract
Heterostructure shows superior catalytic performance since it inherits the catalytic properties of the components, and has the advantages of van der Waals interaction. Herein, we build a vacancy-van der Waals heterostructure with MoTe₂ and WTe₂ which forms a capacitor tuning performance, playing an important role in the energy barrier balance of the catalytic reaction. By using the grand canonical reaction kinetics (GCP-K) to explore the electrocatalytic, we predict the Tafel slope of the HER reaction is 81.31 mV/dec through changing applied potential.
