Abstract
A process for activating the surface of an electrode based on DLC amorphous carbon by an electrochemical treatment including at least the following steps (i) and (ii), carried out in this order: (i) applying, to the electrode, an electrical excitation in the form of an alternation of cathodic and anodic electrical pulses, these being current or voltage pulses, in contact with an aqueous electrolyte including at least one oxidizing species of a redox pair having a standard potential, at ambient temperature and atmospheric pressure, denoted E0, strictly greater than 0, and at least one base salt; and (ii) applying, to the electrode that was previously subjected to step (i), an electrical excitation in the form of an alternation of cathodic and anodic electrical pulses, these being voltage pulses, in contact with an aqueous electrolyte devoid of electroactive species.
