Abstract

The occurrence of the third anodic hydrogen peak was investigated on platinized platinum. Using DEMS in combination with Cyclic Voltammetry it is shown that adsorbed molecular hydrogen is the cause of this third peak. It is suggested that this hydrogen is presented in a subsurface state of Pt since disturbance of the Pt surface structure by oxide formation is necessary for the third peak to appear.
