Transient changes of intermediate species formed during the electrooxidation and surface electroreduction of gold within a monolayer thickness range
Autor: C.M. Ferro, Alfredo J. Calandra, Alejandro Jorge Arvia
Publikováno v: Journal of Electroanalytical Chemistry and Interfacial Electrochemistry. 59:239-253
Summary Evidence for species formed during the anodic oxidation and electroreduction of a gold electrode surface within the range of a monolayer thickness is given by means of triangular potential sweeps run under different experimental conditions. T

The influence of ageing in the kinetics of the electroreduction of gold oxide films of the order of a monolayer thickness
Autor: Alfredo J. Calandra, Alejandro Jorge Arvia, C.M. Ferro
Publikováno v: Journal of Electroanalytical Chemistry. 65:963-988
Gold oxide films of the order of a monolayer thickness are electroreduced under different potentiodynamic conditions. The electrochemical process is coupled to a chemical dissolution of the film and a solid phase transformation. Under controlled agei

The electrochemistry of gold in acetonitrile solutions containing thiocyanate ions
Autor: Alfredo J. Calandra, Alejandro Jorge Arvia, María Elisa Martins, Carlos E. Castellano
Publikováno v: Journal of Electroanalytical Chemistry and Interfacial Electrochemistry. 81:291-300
Gold dissolves anodically in acetonitrile solutions containing dissolved NaSCN, at 25°C. The reaction yields Au(I) and Au(III) complex ion species which can be cathodically electroplated. The voltammetric experiments indicate that the anodic dissolu

The electrochemical behaviour of different graphite/cryolite alumina melt interfaces under potentiodynamic perturbations
Autor: C.E. Castellano, Alfredo J. Calandra, C.M. Ferro
Publikováno v: Electrochimica Acta. 24:425-437
The anodic reaction in molten cryolite alumina systems has been studied in a wide range of potentials by applying both repetitive and single pulse linear sweep voltammetry, varying the sweep rate between 0.04 V/s and 600 V/s, and the alumina concentr

Chronopotentiometric measurements on different graphite/fluoride melt interfaces
Autor: Alfredo J. Calandra, C.E. Castellano, C.M. Ferro
Publikováno v: Electrochimica Acta. 30:1449-1454
The electrochemical behaviour of graphite anodes in pure cryolite and sodium fluoride melts was studied by applying galvanostatic pulses. During the anodic pulse three of four transition times are observed depending on whether cryolite or sodium fluo
