There are found the quantitative link between the electron structure parameters of indicated materials and their catalytic activity on example of a simple model reactions of the following type: H = H+ -f- e and 0 ^ = 0 2 + e~. It has been found that the link between the Fermi level position dependence upon the metal alloy components concentration and their catalytic activity is quite tight.encatalyticmetallicelectrodynamicalsemiconductorArticle
