Abstract
The influence of mechanical activation in a high energy planetary ball mill on hydrogen sorption and structural properties of intermetallic compound LaNi2.5Co2.4Mn0.1 in relation to its application as a filler in composite metal-polymer membranes for hydrogen separation from gas mixtures was studied. It has been determined that the basic results of performed processing are the decrease in the coherent scattering domain size and the increase in lattice microstrain while the unit cell parameters remain unchanged. In the temperature range of 298–333 K, the hydrogen absorption and desorption isotherms were measured, and the values of the related enthalpy and entropy, which do not depend on mechanical activation time, were determined. The results of this work allow us to consider the obtained data as reference values to describe the hydrogen sorption behavior of a metal-hydride component in composite membranes with satisfactory accuracy.
