Voltammetry of 1-bromodecane (concentration: 9 mM) in 0.1 M TBABF₄ using DMF as solvent, recorded at different microelectrodes. Scan rate: 100 mV s⁻¹

(A) Response at a GCE (S = 0.8 mm²)

(B) Response at a freshly made CuPd cathode prepared from a palladium chloride solution (S = 3.2 mm²). First two sweeps

(C) Response at a GCE first covered by a galvanostatic deposit of copper (S = 0.8 mm²) and then treated by palladium sulfate solution. First two steps
