Electrocatalysis for proton reduction by a coated Nafion® membrane dispersing ruthenium moieties
Electrocatalytic proton reduction was studied using Ru-red ([(NH 3) 5Ru IIIORu IV(NH 3) 4ORu III(NH 3) 5]Cl 6) dispersed into a Nafion® membrane coated on a basal-plane pyrolytic graphite (BPG) electrode (denoted as BPG/Nf[Ru-red]) in a pH 1 electrolyte solution. It was found that the Nf[Ru-red]...

Summary: | Electrocatalytic proton reduction was studied using Ru-red ([(NH

5]Cl
6) dispersed into a Nafion® membrane coated on a basal-plane pyrolytic graphite (BPG) electrode (denoted as BPG/Nf[Ru-red]) in a pH 1 electrolyte solution. It was found that the Nf[Ru-red] shows high activity in H
+ reduction to produce H
2. The electrocatalytic reaction by Ru-red embedded in the polymer membrane started to take place by forming catalytically active species after irreversible change of the complex under cathodic conditions. Electrochemical features of the Ru-red in the membrane as well as electrocatalysis by the Nf[Ru-red] for H
+ reduction were discussed based on the results of CV measurement, UV–Vis spectroscopy before and after the electrochemical process and potentiostatic electrolysis. |
