“…The Pd-Cu alloys (4,8,10,15, and 25 at.%Cu as nominal composition) were prepared from the raw materials employing an arc melting method. They will be denoted hereafter as Pd-4Cu, -8Cu, -10Cu, -15Cu and -25Cu for simplicity.…”

“…Among the Pd-Cu alloys examined in this study, thermodynamic parameters for Pd15Cu alloy were almost equivalent to those for Pd-8at.%Pt alloy: DH 0 for absorption of H 2 and D 2 was À29.4 and À26.4 kJ/mol(Q 2 ), and that for desorption of H 2 and D 2 was 30.7 and 28.3 kJ/ mol(Q 2 ), respectively. It is known that this alloy has good performance for separation of a hydrogen isotope mixture near room temperature [10]. It is suggested, therefore, that Pd-15Cu alloy is a promising candidate for an alternative material to Pd-Pt alloys.…”

“…However, most of these techniques have low selectivity for separating hydrogen isotopes. More recently, Matsuyama et al , developed and applied a new separation technique for the separation of hydrogen isotopes, called self-developing gas chromatography. The advantages of this method are operation near room temperature and high efficiency of separation.…”

“…[1][2][3] The property of Pd-Pt alloys is especially useful for the separation of hydrogen isotopes and has been successfully applied for an advanced gas chromatography for hydrogen isotope separation around room temperature without using any replacement gas. [4][5][6] It is reported in our previous papers 7,8) that the heat of hydrogen absorption as well as hydride formation decreases with increasing platinum-content in the alloy. On the other hand, the thermodynamic isotope effect on hydrogen absorption measured by the ratio of equilibrium pressures between protium and deuterium are almost invariable despite the change in the alloy composition.…”
