Adsorption of hydrogen on tantalum in the temperature range 77-373 K

Isotherms of H2 adsorption on a Ta foil were measured over the temperature range 77-373 K at pressures of 0.06-2.0 Pa. Induced- and activated-adsorption modes were revealed. The adsorption isotherms exhibited a maximum near 300 K. Experimental results were treated using a model adsorption isotherm for surfaces with induced nonuniformity. The shape of the isotherms was described by changes in the character of interaction between the adsorbate and the surface electron density of the metal.
