Gas sensing using edge-plane pyrolytic-graphite electrodes: electrochemical reduction of chlorine.
The voltammetric responses of chlorine in aqueous acid solutions have been explored using different carbon-based electrodes.

| Итог: | The voltammetric responses of chlorine in aqueous acid solutions have been explored using different carbon-based electrodes. Edge-plane pyrolytic graphite has more electrochemical reversibility than glassy carbon, basal-plane pyrolytic graphite, or boron-doped diamond electrodes. A significant reduction in the over-potential is observed on the edge-plane pyrolytic-graphite electrode in contrast with the other carbon-based electrode substrates. These results suggest that edge-plane pyrolytic graphite can be optimally used as the working electrodes in Clark-cell devices for low-potential amperometric gas sensing of Cl2. |
