Several key parameters influence the efficiency of HER catalysis:
Overpotential: The additional voltage required beyond the thermodynamic potential to drive the reaction. Current Density: The amount of current per unit area of the catalyst, indicating the rate of hydrogen production. Tafel Slope: A measure of the reaction kinetics, representing the relationship between overpotential and current density. Stability: The long-term durability of the catalyst under operational conditions.
