“…Furthermore, the position of the copper UPD peaks are completely different from those of copper UPD on the electrodeposited palladium layer on Au(111). The copper UPD process on a Pd(100) single crystal electrode was studied in 0.5 M NaClO 4 + 10 -2 M HClO 4 + 10 -3 M Cu 2+ solution and two pairs of sharp peaks were observed at 0.49/0.50 and 0.27/0.29 V [26,27]. The former peaks seem to correspond to the peaks observed in the present study.…”

“…The position and shape of the UPD peak is known to be very sensitive to the surface structure and order [26,27]. After the deposition of palladium in 50 mM H 2 SO 4 solution containing 0.1 mM PdCl 4 2-at 0.7 V for 30 min (ca.…”

“…The CV of copper UPD in a polycrystalline palladium electrode is totally different from these CVs and shows three pairs of redox peaks (+0.26/ +0.27, +0.46/+0.47, and +0.48/+0.49 V) in the same solution. 35 Furthermore, the potentials of the copper UPD peaks are completely different from those of copper UPD on an Au-(111) electrode (+0.56/+0.57 and +0.38/+0.41 V). Thus, it was confirmed that the deposited palladium layer on the Au-(111) electrode was the epitaxially grown Pd(111) phase.…”

“…Desta maneira, este método fornece rapidamente dados termodinâmicos e cinéticos básicos, sendo bastante adequado para a detecção de pequenas quantidades de espécies reativas. Assim, não é surpresa a grande quantidade de trabalhos publicados nesta área utilizando como técnica experimental eletroquímica básica a voltametria cíclica [21][22][23][24][25][26][27][28][29] . No entanto, Swathirajan et al 13 contestam o uso de técnicas eletroquímicas que utilizam apenas um eletrodo de trabalho para este tipo de estudo, pois postulam que o conjunto de dados resultantes não é suficiente para separar os fluxos de massa e de carga no eletrodo.…”
