Description
Nanosecond and microsecond plasmas in liquid will be used to recover a copper oxide surface used as an electrocatalyst. The plasma effects on the surface are analysed in an in-operando system using infrared spectrometry and cyclic voltammetry. An analysis of the plasma and of the plasma-treated liquids complements this.
