Non-uniform current density distribution at a rde. Observation by means of photographing electrochemiluminescence

Equations for the current at a rde have been derived with the presumption that equal accessibility for any place on the electrode surface. An example of non-homogeneous current density distribution at the Pt- rde was observed in photographs of electrogenerated chemiluminescence (ECL) where the inten...

Description
Summary:Equations for the current at a rde have been derived with the presumption that equal accessibility for any place on the electrode surface. An example of non-homogeneous current density distribution at the Pt- rde was observed in photographs of electrogenerated chemiluminescence (ECL) where the intensity of emission changes with the distance from the centre and depends on the type of the process and on the rotation velocity.
