Kinetics of the oxygen evolution reaction on rhodium electrodes with different electrocatalytic activity

It has recently been demonstrated that the potentiodynamic behaviour of Rh/H<sub>2</sub>SO<sub>4</sub>(aq) interphases in the potential range of the thermodynamic stability of bulk water is associated with at least two-well defined and different electrochemical characteristic...

Sumario:It has recently been demonstrated that the potentiodynamic behaviour of Rh/H<sub>2</sub>SO<sub>4</sub>(aq) interphases in the potential range of the thermodynamic stability of bulk water is associated with at least two-well defined and different electrochemical characteristics of rhodium, which were referred to as Aand B-type Rh electrodes. The aim of the present report is to show the electrocatalytic difference of A- and B-type electrodes for the 02 evolution reaction, on the basis that the corresponding structures of the electrodes remain stable during the time the electrochemical measurements last.
