Potentiostatically controlled transient diffusion on solid electrodes with rough surface

- Summary
- Metrics

Abstract

Transient limiting diffusion currents were measured under potentiostatic conditions on several platinum electrodes for various solutions of sucrose with profoundly different diffusivities of a depolarizer. Systematic increase of the current densities against a Cottrellian (penetration) asymptote is correlated with parameters of roughness description.
