本研究报告了锂原子渗透到 Pd 表面对 Pd-H 体系的压力-组成-温度关系以及氢反应热的影响。即使在 353 K 的温度下，Pd 在 1 M LiOH 溶液中的热处理也会诱导 Li 原子渗透到 Pd 中。氢固溶体的形成显着增强约 90-100%，PdH1−x 氢化物相的形成约增强 29%，这似乎归因于预处理过程中氢与从 LiOH 渗透的 Li 原子的强烈相互作用。
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−xhydride phase seems to be attributed to strong interactions of hydrogen with the Li atoms penetrated from the LiOH during the pretreatment.
