摘要
This study reports the effect of the penetration of Li atoms into the Pd surface on the pressure-composition-temperature relation of the Pd-H system and on the heats of reactions of hydrogen. A heat treatment of Pd in a 1 M LiOH solution induces the penetration of Li atoms into Pd even at 353 K. The marked enhancement about by 90-100% for the formation of hydrogen solid solution, and about by 29% for the formation of PdH1-x hydride phase seems to be attributed to strong interactions of hydrogen with the Li atoms penetrated from the LiOH during the pretreatment.
