“…From the electrochemical point of view, the oxygen evolution on perovskites has been the object of extensive study (12,13,(21)(22)(23) but there is a lack of experimental works which attempt to electrochemically characterize the La CuO phase in alkaline solution. The present study brings another view to this frame, with the help of electrochemical methods to systematically investigate the surface reactions of La CuO phases, including oxygen evolution and adsorption after oxidation in alkaline solution at 295 K. An attempt to link the electrochemistry of the La CuO oxidation phenomenon with the oxygen intercalation in the oxide bulk has also been made.…”

“…(2)) is the contrary, the Heyrovsky step will control the hydrogen desorption sooner or later with increasing of overpotential. Bockris et al supposed the change of mechanism from the V-H route to the V-T route on Pd with rise of cathodic overpotential [22], but it is readily understood from our discussion that this cannot take place.…”

“…Como demonstrado na Figura 1, a eletrólise indireta combina uma etapa heterogênea, que é a formação e regeneração do catalisador redox na sua forma ativa na superfície do eletrodo, com uma reação redox homogênea do substrato com o mediador ativo. e-mail: carrijo@ufu.br e-mail: jrromero@usp.br Este método eletroquímico tem sido largamente aceito e tem se desenvolvido bastante nos últimos 30 anos 20,21 . A regeneração eletroquímica do mediador pode ser feita através de três caminhos diferentes: out cell 17,19 , in cell 19,22 e utilizando-se eletrodo modificado 23 , onde os dois primeiros se referem a processos homogêneos, pois a troca de elétrons entre o mediador e o substrato se dá em solução.…”
