Carbon ring electrode characterization

Carbon ring electrodes with structurally ultrasmall tip diameters were fabricated as described elsewhere. Electrodes with 3-5 pm tip diameters were used for intracellular voltammetry. Electrodes used for characterization ranged from 3 to 15 im in tip diameter. [Pg.418]

In a rotated ring-disk electrode experiment where the disk is controlled at +2.6 V versus SCE for the oxidation of HOOH and the ring electrode is controlled at -1.4 V versus SCE for the reduction of the oxidation products from HOOH, the observed collection efficiency (N = /r//d) is 0.384. This is slightly less than the theoretical value of 0.418 for the electrode. The products from HOOH oxidation at the glassy-carbon disk electrode (ED, + 2.6 V vs. SCE) can be characterized at the ring by scanning its potential from +1.0 to... [Pg.81]
