(A) Cyclic voltammogram for CueO immobilized on bare GC upon cycling in an O2 saturated sodium PBS, pH 6.5. (a) Blue line: 1st cycle. (b) Dark yellow line: 22nd cycle. (The arrow indicates the evolution from the first to the 22nd cycle). (c) GC blank in Ar atmosphere (black line). (d) GC blank in O2 atmosphere (Red line). (B) Cyclic voltammogram for CueO immobilized on bare GC in an Ar PBS, pH 6.5, after 22 cycles. (C) (a) First cyclic voltammetric curve for CueO (activated in Ar) in an O2 saturated PBS, pH 6.5, blue line: 1st cycle. (b) GC blank in Ar atmosphere (black line). (c) GC blank in O2 atmosphere (red line). Scan rate: 20 mVs−1.
