Surface redox activities, oxygen evolution reaction (OER), oxidation of formic acid (FA), and anodic stability were investigated and compared for IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor (TDIROF) and the an ...
In this paper, the IrO2 electrode preparation technique consisting in thermal treatment of pure Ir in air was used in order to produce an IrO2-based microelectrode-array (TOIROF-MEA) with low capacitive background current. The TOIROF-MEA was characterized ...
The electrochemical behaviour of ammonia (NH4+/NH3) in sodium perchlorate at pH 9 has been investigated on electrochemically grown anodic iridium oxide film (AIROF) electrode. In base electrolyte at pH 9, the Ir(IV)/Ir(III) surface redox couple exhibits un ...
