ELECTROCHEMISTRY OF FUEL CELL ELECTRODES. SURFACE OXIDATION OF GOLD ELECTRODES
Abstract
The surface oxides formed on electropolished gold by potentiostatic anodization in the range 1.2 1.8 v vs. H(+)/H2 in the same solution, were studied by galvanostatic reduction at current densities between 10 and 1000 microamperes/sq cm. Molar perchlorate solutions of pH 0.04 to 2.1 were employed. The extent of oxide formation is determined by the potential of anodization, the charge increasing linearly with the potential of formation in the range of 1.4 to 1.8 v. Cathodic chronopotentiograms show that reduction of the oxide occurs at a definite potential which depends on the cathodic current density. (Author)
