摘要：

A method using foreign metal adatoms is proposed for distinguishing adsorbed and dissolved hydrogen in palladium electrodes. It is shown that the solubility of hydrogen in the a phase of different dispersed palladium samples is higher than that in smooth Pd and increases as the dispersity increases. On the basis of the Bucur model, a quantitative estimate is made of the structural defectiveness of the palladium dispersed forms investigated.
