Cyclic voltammogram for the catalysis of the ORR by immobilized CueO on Au(111) after protein submission to −0.1 V during 1 min (A), 5 min (C), and 10 min (E). Monitoring of the CueO current density with time while protein submission to −0.1 V during different periods of time: 1 min (B), 5 min (D) and 10 min (F). Scan rate: 20 mVs−1.
