Several factors can influence Warburg impedance in catalytic systems:
1. Concentration of Reactants and Products: Higher concentrations generally lead to lower Warburg impedance due to increased ion mobility. 2. Temperature: Elevated temperatures enhance ion diffusion, thereby reducing Warburg impedance. 3. Electrolyte Composition: The type and concentration of the electrolyte can significantly affect ion transport and thus the Warburg impedance. 4. Catalyst Structure and Morphology: The surface area, porosity, and other structural properties of the catalyst can impact the diffusion pathways and, consequently, the Warburg impedance.
