Rotating Disc Electrode (RDE) is a hydrodynamic working electrode used in electrochemical applications such as corrosion studies, fuel cell research, catalyst development, and controlling mass transport of reactants to the electrode surface. The electrode rotates during experiments, making a constant flux of analyte to the electrode. As the disk turns, some of the solution described as the hydrodynamic boundary layer is dragged by the spinning disk and the resulting centrifugal force flings the solution away from the center of the electrode. This flow can quickly achieve conditions in which the steady-state current is controlled by the solution flow rather than diffusion.

FAQ
What is rotating disk electrode used for?
Rotating disk electrode (RDE) is a hydrodynamic working electrode used in electrochemical applications such as corrosion studies, fuel cell research, catalyst development, and controlling mass transport of reactants to the electrode surface. It is used when defined mass transport to the sample electrode is desired. The disk's rotation induces a constant flux of analyte to the electrode, making it ideal for investigating different electrochemical phenomena such as multi-electron transfer, kinetics of slow electron transfer, adsorption/desorption steps, and electrochemical reaction mechanisms. In analytical chemistry, RDE is used in three-electrode systems for hydrodynamic voltammetry to investigate reaction mechanisms related to redox chemistry.
What is the rotating electrode method?
The rotating electrode method is a technique used in electrochemical applications such as fuel cell research, corrosion studies, catalyst development, and controlling mass transport of reactants to the electrode surface. It involves using a rotating disk electrode (RDE) that rotates during experiments, inducing a constant flux of analyte to the electrode. The RDE can quickly achieve conditions in which the steady-state current is controlled by the solution flow rather than diffusion. By running experiments at various rotation rates, different electrochemical phenomena can be investigated, including multi-electron transfer, adsorption/desorption steps, and electrochemical reaction mechanisms.
What is the rotating ring-disk electrode method?
The rotating ring-disk electrode (RRDE) is a double working electrode used in analytical chemistry for hydrodynamic voltammetry. It is designed for investigating reaction mechanisms related to redox chemistry and other chemical phenomena. The RRDE has a disk electrode at its center and a ring electrode around the disk. The system takes advantage of the laminar flow created during rotation, allowing for controlled contact of the solution with the disk and ring electrodes. By varying the rate of rotation, it is possible to determine the rate of the chemical reaction and investigate different electrochemical phenomena.
What are the advantages of rotating disc electrode?
The advantages of rotating disk electrodes (RDE) include the ability to control mass transport of reactants to the electrode surface, achieve laminar flow of solution towards and across the electrode, and investigate different electrochemical phenomena such as multi-electron transfer and electrochemical reaction mechanisms. RDEs are commonly used in electrochemical applications such as corrosion studies, fuel cell research, and catalyst development. The base rotation rate of RDEs can be manually adjusted, and the electrode rotation rate can be precisely controlled with an electric motor. RDEs are a powerful tool for investigating reaction mechanisms related to redox chemistry and other chemical phenomena.
