Summary Cyclic voltammograms of platinum and iridium electrodes in 5 M sulphuric acid at −72°C display much greater separation of the hydrogen adsorption and evolution currents than at 20°C. This enables the saturation hydrogen coverage and the real surface area of an electrode to be determined directly from the voltammogram. The adsorption of hydrogen on rhodium is not sufficiently rapid to maintain equilibrium on a voltammogram at reduced temperatures, and the saturation hydrogen coverage… CONTINUE READING
