What Techniques are Used to Study the Electrode-Electrolyte Interface?
Several analytical techniques are employed to investigate the properties of the electrode-electrolyte interface:
1. Electrochemical Impedance Spectroscopy (EIS): This technique measures the impedance of the interface, providing information about charge transfer resistance and double layer capacitance. 2. Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM): These provide high-resolution images of the electrode surface, allowing for the study of surface morphology and structure. 3. X-ray Photoelectron Spectroscopy (XPS): This technique analyzes the surface composition and oxidation states of elements at the interface. 4. Cyclic Voltammetry (CV): Used to study the electrochemical behavior and identify reaction mechanisms at the interface.
