What is a Rotating Ring-Disk Electrode?
A Rotating Ring-Disk Electrode (RRDE) is a specialized electrochemical instrument used in analytical chemistry. It is a double working electrode that consists of a rotating disk electrode and a ring electrode. The RRDE is used in hydrodynamic voltammetry, where it rotates during experiments to induce a flux of analyte to the electrode.
Background on Electrochemical Studies
Electrochemical studies involve the use of electrodes to investigate chemical reactions, particularly those related to redox chemistry. Redox chemistry is the study of chemical reactions that involve the transfer of electrons, such as oxidation and reduction reactions. Electrochemical studies are crucial in understanding reaction mechanisms, and the RRDE is a valuable tool in this field.
