Abstract

Ellipsometry is applied to study the oxidation of platinum in sulfuric acid solution. Steady‐state and transient measurements show that oxide‐film formation commences when the potential is anodic to 0.95 V. The film is light absorbing. The film thickness increases linearly with potential. A mechanism of film growth based on place exchange is developed.
