What are the Common Electrochemical Techniques Used?
Several electrochemical techniques are commonly employed in catalysis research:
1. Cyclic Voltammetry (CV): This technique involves sweeping the potential of an electrode linearly with time to study the redox behavior of catalysts. It provides information on the oxidation and reduction potentials and the catalytic activity.
2. Linear Sweep Voltammetry (LSV): Similar to CV, LSV involves a linear potential sweep but in a single direction. It is used to determine the onset potential and the catalytic current.
3. Electrochemical Impedance Spectroscopy (EIS): EIS measures the impedance of a system over a range of frequencies to analyze the charge transfer resistance, double-layer capacitance, and other interfacial properties.
4. Chronoamperometry and Chronopotentiometry: These techniques involve applying a constant potential or current, respectively, to study the time-dependent behavior of the catalyst.
