Abstract:

The surface oxides formed on electropolished gold by potentiostatic anodization in the range 1.2 1.8 v vs. HH2 in the same solution, were studied by galvanostatic reduction at current densities between 10 and 1000 microamperessq 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
