Electrochemical device for the determination of sulfur dioxide in the air and process gas media
Developed gas diffusion catalytically active 3D-electrodes based on valve metal having a two-level three-dimensional structure comprising a microporous composite electrocatalytic coating applied to a discontinuous basis, and a porous regular of the electrode structure, which may include both electrocatalytically active material, and a mixture of the latter with other disperse materials.
