Using solvents to control hydrogen adsorption on skeletal nickel

The results from adsorption-calorimetric studies of hydrogen adsorption on skeletal nickel are generalized. The thermodynamic characteristics of adsorbed hydrogen are calculated according to the model of an ideal surface with discrete heterogeneity. It is shown that the states of surface layers in solutions, formed upon hydrogen adsorption on skeletal and porous nickel, depend on the nature and composition of the solvent. Based on the resulting data, the possibility of using a solvent to control adsorption in a skeletal nickel-hydrogen system is confirmed.
