The performance of electrodes in catalytic applications is evaluated using several metrics:
- Overpotential: The extra voltage required to drive a reaction at a significant rate compared to the theoretical minimum. - Current Density: The amount of current per unit area of the electrode, indicating the rate of the catalytic reaction. - Faradaic Efficiency: The efficiency with which charge is transferred in a desired electrochemical reaction. - Stability Tests: Long-term tests under operational conditions to assess durability.
