Rotating Ring Disk Electrode (RRDE)
Powerful RDDE for Revealing Intermediates & Quantifying Reaction Pathways
Used in fuel cell catalysis, sensor development, corrosion studies, and electroplating
Overview | Specifications | Related Products | Resources and Support
The rotating ring disk electrode (RRDE) is a powerful electrochemical electrode that consists of two concentric, independently controlled electrodes with a central disk and a surrounding ring, separated by an insulator. The central disk serves as the primary and the ring serves as the secondary working electrode, respectively. By rotating together, the central disk and the ring create a controlled flow that pulls reactants to the disk and then carries them radially outwards to the ring. RRDE is engaged to study reaction mechanisms by generating products at the disk and detecting them at the ring, revealing intermediates and quantifying reaction pathways.
As a quantitative in situ electroanalytical detection tool, a rotating disk electrode can be used in fuel cell catalysis like oxygen reduction reactions (ORR), sensor development, corrosion studies, electroplating, and understanding fundamental redox chemistry. They help determine reaction steps, selectivity, diffusion coefficients, and catalyst efficiency by separating kinetic and mass transfer effects, making them vital for catalysis research and advanced materials science. The Ossila Rotating Ring Disk Electrode is compatible with relevant Pine products*.
