CV curves recorded at 50 mV·s−1 from 5 mM Bi(NO3)3·5H2O + 1.5 M HNO3 + x M NaC6H11O7 with (a) x = 0 onto different substrates in stagnant conditions; (b) x = 0 onto Si/Ti/Au in stagnant and Ar-bubbling conditions (initiated at the crossover toward positive potentials as indicated by the dashed arrow); and (c) x = 0 and x = 0.05 onto Si/Ti/Au in stagnant conditions.
