Abstract

The spatial current distribution associated with the oscillatory behavior of a nickel wire in sulfuric acid solution has been investigated. The time-dependent local activity has been resolved using a microcomputer-controlled set of micro-reference electrodes situated close to an anodized nickel wire. Galvanostatic potential oscillations are accompanied by standing activity waves, while the almost potentiostatic oscillations are accompanied by travelling pulses. The long-range synchronization along the electrode exhibits chaotic behavior. Transitions between steady states show long-range current modulation instead of the expected moving fronts.
