What Techniques are Used in Electrochemical Studies?
Several techniques are employed in electrochemical studies to analyze catalytic processes:
1. Cyclic Voltammetry (CV): This technique measures the current response of a catalyst to a linearly varying voltage, providing information about redox processes and reaction kinetics. 2. Electrochemical Impedance Spectroscopy (EIS): EIS measures the impedance of a system over a range of frequencies, helping to dissect complex reactions and understand the resistance and capacitance of different components. 3. Chronoamperometry and Chronopotentiometry: These methods apply a constant potential or current and monitor the resulting current or voltage over time, respectively, to study the stability and activity of catalysts. 4. Rotating Disk Electrode (RDE) and Rotating Ring-Disk Electrode (RRDE): These techniques involve rotating electrodes to control mass transport and study the kinetics of catalytic processes.
