Although not as efficient as Pd, Nb and Ta coating layers can nevertheless provide a reasonable H(2) dissociation and recombination rates. Thereduced values of hydrogen permeabilityin comparison to that of Pd were explained by the reduced catalytic properties of Nb and Ta and the formation of hydrides on the surface.
